Quo Vadis Business Simulation Games in the 21st Century?

: Business simulation games have become popular in higher education and business environments. The paper aims to identify the primary research trends and topics of business simulation games research using a systematic and automated literature review with the motivation of research (learning driven and domain driven). Based on these ﬁndings, the future development of business simulation games research projected papers that research business simulation games were extracted from Scopus. Second, the research timeline, main publication venues and citation trends have been analysed. Third, the most frequent words, phrases, and topics were extracted using text mining. Results indicate that the research on business simulation games has stagnated, with the most cited papers published in the 2000s. There is a balance between learning-driven and domain driven-research, while technology-driven research is scarce, indicating that the technology used for business simulation games is mature. We project that the research on business simulation games needs to be directed in the area of new technologies that could improve communication with and among the users (virtual reality, augmented reality, simulation games) and technologies that could improve the reasoning and decision-making complexity in business


Introduction
With the establishment of simulation games in the 1950s, their production has expanded dramatically, as has the usage of simulation games in formal and informal education.Higher education institutions started integrating simulation games into their courses in the mid-60s to provide an active learning experience to the students [1].Since then, simulation games have been widely employed to boost students' learning, using both general and tailored simulation games [2].Further growth of simulation game usage in education occurred in the 21st century, additionally driven by mobile technology [3].According to the Global Opportunities and Industry Forecast 2020-2027 research, the simulation and virtual training market was worth $204.41 billion in 2019 and is projected to reach $579.44 billion by the end of 2027 [4].
Modern generations, such as Generation Z, demand changes in learning processes suited for the new digital era.Generation Z strives for informal learning and is interested in using various new information and communication technologies in the educational process [5,6].Applying game elements, such as simulation games, within the educational process is one of the major innovative ways to motivate students, which is especially important in business and management education [7].Business simulation games allow students to learn by experiencing different situations in a simulated environment.In addition to their usage in formal learning, business simulation games are often used in informal learning, such as business professionals, who first make business decisions in a simulated environment to improve their decision-making skills and avoid mistakes in real business settings [7].
simulated environment to improve their decision-making skills and avoid mistakes in real business settings [7].
This change has naturally led to increased scientific research on business simulation games [8].Several systematic literature reviews were conducted about business simulation games.The first group of reviews focuses on a narrow group of business simulation games, focusing on a specific business function, such as decision support systems [9], project management [10], and business process change [11].The second group of reviews focus on the learning outcomes and is driven by specific research questions, such as empirical evidence of learning and effective teaching [4] and the impact of simulation games on capabilities in decision-making and cognitive skills [12].The third group of reviews focus on the usage of specific technology, such as neuroscience research devices [13,14] and virtual reality [15].These groups of reviews can be referred to as domain-driven, technology-driven, and learning-driven research.However, the limitation of these reviews is that they focus on a single topic, engaging in a microlevel analysis focusing on a narrow aspect of business simulation games.Only one review could be considered a macrolevel analysis [4], but it did not include all topics related to business simulation games.
The current literature reviews were mostly applied as systematic literature reviews (SLRs), using standard formats such as Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), which is time-consuming, causing their narrow focus.Automated literature reviews (ALRs) using natural language processing, such as word extraction, phrase extraction, and topic mining, overcome the barriers of SLRs [16].Using ALRs allows the unstructured analysis of research papers, allowing the broad macrolevel analysis, which leads to the extraction of a broad range of topics, thus overcoming the narrow focus of SLRs.
The current study uses a mixed approach, combining SLR and ALR to analyse the research on business simulation games to address the gaps mentioned above and deliver a wider perspective on the research trends and perspectives.This work combines computational and qualitative methods to identify important research themes, examine temporal trends of those issues over the past several decades, and suggest viable future avenues in business simulation games research.This article discusses the subsequent research questions: What are the primary research trends and topics in business simulation games research?What is the balance between learning-driven and domaindriven research topics?The answers to both questions will be used for developing the future development of business simulation games research (Figure 1).The paper has several contributions.First, to the best of our knowledge, this is the first study to analyse research on business simulation games using the combined SLR and ALR approach.Second, the proposed framework for data analysis is a versatile method applicable to numerous research topics.Thirdly, this work can shed light on previous and future research on business simulation games by examining the most important research trends and themes from 1973 to 2023.
To achieve the specified objective of the study, this paper is organised as follows.The first part of the paper delivers an introduction to the selected theme.After the introduction, the theoretical background is given in the second part of the paper, presenting the background for investigating simulation game perspectives in several fields.The third part of the paper refers to the methodology used in the paper.The fourth part of the paper presents the results obtained by the mixed research methods.Finally, in the fifth part of the paper, final concluding remarks, limitations of the paper, as well as recommendations for further research are provided.

Simulation Games
Simulation can be defined as an already-known process from the real world, represented in a safe, non-mistakable environment [17].It is generated by a mathematical/algorithmic model allowing numerous diverse solutions for different situations of the presented process [18].Furthermore, the simulation represents a methodology that supports recognising and understanding the relationship between entities and other components of the same process [19].Namely, simulation represents the specific model for testing, evaluating, and using simulated processes in reality [19].On the other hand, the game can be defined as a simulative, virtual environment for attaining the most attention of the player in specific situation/s [17].Additionally, the game motivates the player to achieve the best score based on their performance and provides the player with experiences of win or loss scenarios [17].According to [20], the game is founded on several components such as (i) mechanics that define the main aim of each game; (ii) stories that define the process flow of the game; (iii) aesthetics that represent the optical, auditory, and emotional sense of the player for each game; and (iv) applied technologies that provide physical support for using the game.
Many authors still need to debate using both terms, simulation and game, as one concept due to their differences in objectives and characteristics [21].However, numerous authors defined and described simulation games from different perspectives over time, but, persistently, they observed it as one concept called "simulation games".Nowadays, in academic circles, it is also common to use the term "digital simulation games" for simulation games since many of them are mostly supported by a digital platform or by some other digital tool or software [21].
Simulation games are designed to combine the virtual and the real world.The simulation game design encloses the conceptual content establishment and the game process development that together support predefined game objectives.It is also significant to comprehend that the process flow of designing games is moving forward from the real to the virtual (game) world while applying the game proceeds from the virtual (game) to the real world [22].According to the authors of [23], a simulation game is a mash-up of game and simulation elements representing rivalry, collaboration, rules, participants, and characters with powerful, real-world features.Furthermore, simulation games support mutual communication between game participants [24].Therefore, simulation games bring real real-world problems closer to the player and make it easier for the player to solve them [24].
Various authors emphasise the role of simulation games in the educational system, e.g., [17,25,26].For example, the authors of [27], in their study from 1989, highlighted the 30 year-long application of business simulation games for learning and teaching purposes.Their widespread utilisation in education stems precisely form the goals of simulation games, which are always in some way oriented toward learning new processes, phenomena, etc. [24,28].According to the authors of [9,22], simulation games allow students to experience the real world in a "safe, simulated" environment.In that way, simulation games encourage students to acquire new knowledge interestingly through practical work and active participation in solving certain problems [9,22].Similarly, the authors of [21] argue in their work about how simulation games use the scenario-based technique to support students in applying existing knowledge and gaining new knowledge within a certain situation/problem.In addition to motivating students to acquire new knowledge, simulation games also improve learning efficiency, enhance students' performance in the education system, and facilitate quality communication between students [29].

Business Simulation Games
The first business simulation game, Monopologs, appeared in 1955 and was developed by Rand Corporation and based on experiencing the U.S. Air Force logistics system [30,31].Over time, the development of different business simulation games for various purposes increasingly progressed due to the strong research and practice interest in their utilisation possibilities [27].According to the authors of [23], business simulation games are used for numerous purposes but are most recognisable in the education sector as a tool for teaching and learning.However, over time, more organisations are recognising the importance of simulation games' role in business management and are starting to use business simulation games to achieve certain business goals [23].Therefore, business simulation games today acquire their role in different human life fields such as information technology, learning, teaching, strategic and operations management (business decision-making), accounting, medicine, administration, engineering, etc. [17,22,24,[31][32][33].Disciplines that are, at first sight, outside of the scope of business are also often the topic of the simulation's research, which can be the basis for the simulation games' development, such as health care [34], sustainable urban development [35], business process management [36], enterprise resource planning [37], investments [38], and knowledge management [39].
The obstacles and perspectives of business simulation games are relevant to research topics since they reveal the problems and perspectives of their implementation in higher educational institutions and business entities [40,41].
Research on business simulation games can be domain driven, technology driven, and learning driven.
Domain-driven research on business simulation games focuses on a specific field of business.Numerous authors investigate the role of simulation games and their importance in learning various domains, such as economics, finance, and the business management of different organisations, e.g., [31,42,43].For example, the authors of [44] accentuate the importance of simulation games in learning business finance.However, in addition to the education field, the authors of [31] emphasise how papers dealing with business simulation games are also linked to research topics such as decision-making, teamwork and similar experience gaining, and strategy development.Similarly, the authors of [42] accentuate how quality business strategy establishment and successful business process management depend on simulation games.According to the organisational level, simulation games are mostly domain driven and can be divided into three categories: (1) top management business simulation games focused on gaining management experience; (2) functional business simulation games oriented to take on a role in one of the organisation's departments; and (3) concept business simulation games relating to taking on a role in the management of a particular business concept such as sales [31].
Technology-driven research on business simulation games focuses on a specific technology used in a simulation game design, such as neuroscience research devices [13,14] and virtual reality [15].
Learning-driven research on business simulation games focuses on the impact of simulation games on formal and informal learning.Research in this area is vast.In their work, the authors of [32] stress that applying simulation games were the key determinant for achieving quality decision-making processes and increasing teamwork effectiveness.According to the authors of [21], simulation games ensure higher levels of analytical, strategic, problem solving, social, and communication skills among employees, enhance the possibility of making quality and efficient negotiations, and support gaining mutual knowledge and making decisions within the team.Accordingly, simulation games can be used in the organisation to train employees to work in new systems, which, in turn, can facilitate the adoption of new information systems in organisations [9].Learning-driven research on business simulation games can be divided into two categories: (1) research on business simulation games as a teaching tool that helps teachers to present and explain complex concepts to facilitate presentation, analysis, and evaluation of business problems; and (2) research on business simulation games as a training method which enables students to acquire new skills, the application of which will solve a certain business problem in a safe and fast way in reality [23].
Domain-driven and learning-driven approaches are, in some cases, combined.For example, the authors of [10], in their work, refer to some of the previously mentioned skills that are comprised within the project management field (e.g., negotiations, problem-solving skills, decision making, etc.), which have also been improved in people who have used simulation games to learn to manage projects more effectively.
Bearing in mind all facts mentioned above in the theoretical part of the paper, a need for synthesised literature on the chosen topic and more detailed knowledge of the fields where business simulation games are applied and investigated arises.Accordingly, a bibliometric analysis is conducted, followed by text and topic analysis of papers published on business simulation games.

Methodology
A mixed-method approach combining SLR and ALR was used to fulfil the paper's goals and obtain deep knowledge.

Systematic Literature Review
SLR refers to the process of a stand-alone literature review conducted systematically, formally, and rigorously [45].SLR was conducted by searching the literature within the Scopus database as one of the most prominent indexing service engines [46].Figure 2 represents the stages of SLR.In the first step of the search process, the keywords "business simulation game" OR "management simulation game" were used.The search covered title, abstract, and keywords, and the timespan was all years (from 1955 to 2022).In the first step, 349 documents were extracted.Among these documents were 14 conference reviews, 1 book, 1 retraction, 1 note, and 1 erratum.In the second step, the search process was restricted by specific research fields, excluding conference reviews, books, retractions, and erratus, resulting in the extraction of 332 papers published in journals, book chapters, and Step 1 •Keywords used: TITLE-ABS-KEY ( "business simulation game" OR "management simulation game" ) •Restrictions: no restrictions •Result: 349 documents Step 2 •Restrictions: journal papers, conference papers, and book chapters

• Keywords used: "TITLE-ABS-KEY ( "business simulation game" OR "management simulation game" ) AND (EXCLUDE ( DOCTYPE , "cr" ) OR (DOCTYPE , "bk" ) OR (DOCTYPE , "er" ) OR (DOCTYPE , "tb" ) )
• Result: 332 papers for furthere analysis Step 3 •Timeline of publications •Most frequent research areas and countries •Most frequent journals, conference proceedings, and book series •Most frequent scientific fields and most cited articles In the first step of the search process, the keywords "business simulation game" OR "management simulation game" were used.The search covered title, abstract, and keywords, and the timespan was all years (from 1955 to 2022).In the first step, 349 documents were extracted.Among these documents were 14 conference reviews, 1 book, 1 retraction, 1 note, and 1 erratum.In the second step, the search process was restricted by specific research fields, excluding conference reviews, books, retractions, and erratus, resulting in the extraction of 332 papers published in journals, book chapters, and conference proceedings.In the third step, bibliometric analysis was conducted, including a timeline of publications, most frequent research areas and countries, most frequent journals and conference proceedings, book series, most frequent scientific fields, and most cited articles.

Automated Literature Review
In the second stage, ALR was conducted using a text mining approach, automatically extracting comprehensive information from text [47].
Wordstat was used for text mining analysis [48].Scientific articles were mined for valuable information, patterns, nontrivial knowledge, and trends using word, phrase, and topic extraction [49].
First, the most frequent words were extracted from the papers.Second, the most frequent phrases were extracted from the papers.To provide a timeline of the research, phrases were analysed concerning the year of the paper's publication.Third, topic mining was conducted using cluster analysis, which was performed using the average-linkage hierarchical clustering algorithm [50].The distance between two clusters represents the medium distance between each observation in one cluster and every other observation.The dendrogram defines only the temporal order of the branching sequence; the sequence of phrases cannot be interpreted as a linear representation of those distances [51].Therefore, any cluster on the dendrogram can be rotated across its branches without affecting its signification.The extracted information is visually presented in word clouds, bubble plots, and dendrograms [52].
Figure 3 represents the stages of ALR.

The rest of the ten most-cited papers are related to education, followed by business and management, and one paper explains the taxonomy of the given topic.
Primary research motivation was also investigated.It can be concluded that half of the most cited papers are dominantly learning driven, the other half were domain driven, and none were technology driven.

Automated Literature Review
This part of the paper presents the results of ALR: (i) the most frequent words; (ii) the most frequent phrases; and (iii) the extracted topics of the research.
Table 5 presents the extraction of the words with the highest occurrence in the empirical papers.The analysis did not include words directly related to the topic of research such as simulation, business, and management.The highest TF-IDF value has the word "learning", which occurs 720 times.Among the top ten most frequently mentioned words in the observed papers are words such as "students", "research", and "education", which are related to the topic itself, and they appear in more than 50% of observed papers.Furthermore, among the top ten most frequently mentioned words are words such as "decision", "knowledge", and "teaching", which pinpoint the interconnection of the observed topic with education and research.
Among the most frequently mentioned words are also words that connect the topic to the educational process, as well as the words such as "performance", "development", and "design", which relate the selected topic to business performance and the connection to the practice.
Research motivation (learning driven, domain driven, and technology driven) was not investigated due to the generic nature of extracted words.
Figure 9 shows word cloud visualisation of the words with the highest occurrence among the selected papers.Table 6 presents the phrase extraction of the phrases with the highest occurrence in the selected papers to develop further in-depth knowledge of the business simulation games and the application fields.The phrase with the highest frequency and TF-IDF index indicating relevance is "decision making", which occurs 96 times in the 48 research papers emphasising the relevance of the simulation games for decision-making training."Supply Table 6 presents the phrase extraction of the phrases with the highest occurrence in the selected papers to develop further in-depth knowledge of the business simulation games and the application fields.The phrase with the highest frequency and TF-IDF index indicating relevance is "decision making", which occurs 96 times in the 48 research papers emphasising the relevance of the simulation games for decision-making training."Supply chain" is the second phrase with the highest frequency in the selected papers, which occurs 66 times in 22 papers.The third phrase with the highest frequency is "learning outcomes", which occurs 60 times in 29 papers.The top ten most frequently used phrases are mostly domain driven, such as "higher education", "experiential learning", "learning environment", "real world", and "teaching and learning".However, several phrases are domain driven, such as "decision support systems", "entrepreneurship education", "sustainable development", "enterprise resource planning", and "football manager".Primary research motivation was also investigated.It can be concluded that most of the frequent phrases are dominantly learning driven; several were domain driven, while, again, none of the papers were technology driven.Figure 10 shows word cloud visualisation of the phrases with the highest occurrence among the selected papers.For instance, the most frequently occurring phrase listed in Table 6 (decision making) is first mentioned in the paper published in 1973.Still, it is mostly mentioned in novel publications, demonstrating its relevance in recent years.Most of the phrases have occurred more frequently during the last ten years, with only a few mentions in earlier publications.Papers with learning-driven phrases related to education and learning have a constant interest.
Table 7 presents the highest frequency keywords per publication year, highlighting the most important keywords at the given period.The table shows that the different periods concentrate on different aspects of the business simulation games.For instance, papers from 2000 to 2005 focused on sustainable development, virtual teams, and real-world research and learning environments.That indicates that businesses adopted simulation games firstly for decision-making support.From 2005, the investigation focused on higher education and learning management from 2005 to 2010 could be described as knowledge driven.The next decade shows the expansion of interest in the topic from different aspects.It introduces various business simulation games in several domains, such as information systems, entrepreneurship, sustainable development, enterprise resource planning, and football.The papers from 2015 explore business simulation games from numerous perspectives, according to the current state of business, education, and technological development.For instance, the most frequently occurring phrase listed in Table 6 (decision making) is first mentioned in the paper published in 1973.Still, it is mostly mentioned in novel publications, demonstrating its relevance in recent years.Most of the phrases have occurred more frequently during the last ten years, with only a few mentions in earlier publications.Papers with learning-driven phrases related to education and learning have a constant interest.

Figure 13 presents the mapping of clusters and cluster phrases, indicating the relevance and cohesion of the cluster items.A careful review of abstracts and the full text was performed to understand ea cluster better.As a result, the cluster reflects the most important aspects of busine  A careful review of abstracts and the full text was performed to understand each cluster better.As a result, the cluster reflects the most important aspects of business simulation games utilisation (Table 8).Most clusters are domain driven (6 clusters), followed by learning-driven research (5 clusters).None of the clusters contained phrases A careful review of abstracts and the full text was performed to understand each cluster better.As a result, the cluster reflects the most important aspects of business simulation games utilisation (Table 8).Most clusters are domain driven (6 clusters), followed by learning-driven research (5 clusters).None of the clusters contained phrases that would indicate technology-driven research.Following the analysis of clusters in terms of extracted phrases and primary motivation of the research, two groups of clusters are extracted: (i) Learning-driven, which contains Cluster 1 (Knowledge management), Cluster 2 (Learning environment), and Cluster 6 (Design methods), which refers to both to academic and business which use simulation games as a learning tool for student and employee's education, and business goals.(ii) Domain-driven consists of Cluster 3 (Business games), Cluster 4 (Decision-making games), Cluster 5 (Project management games), and Cluster 7 (Firm performance games).Papers in this group often include case studies of the different simulation games or investigations of application fields of simulation game utilisation, as well as publication papers that describe simulation games as decision making, firm performance, and project management tools.The presented simulation games' perspectives are shown in Figure 14.

Conclusions
Business simulation games are widely used both in high education and in business.This paper aims to identify the relevance and profoundly explore the existing literature to develop in-depth knowledge and extract patterns and the most important findings.The research goals were to provide insight into the research trends and topics in business simulation games' research and to investigate the balance between learning-driven and domain-driven research topics.The analysis is the basis for the projections of future developments in business simulation games research.
The paper contains several contributions.Firstly, by combining SLR and ALR, the current study analyses the research on business simulation games to solve the gaps mentioned above and provide a broader perspective on the research trends and perspectives.This paper combines computational and qualitative methodologies to identify significant study themes, examine the temporal trends of these concerns over the past several decades, and suggest possible future pathways for business simulation games research.
Secondly, the suggested data analysis framework is flexible and adaptable to various study areas.In addition to combining the SLR and ALR methods, we introduce the concept of the primary motivation in business simulation research, including learningdriven, domain-driven, and technology-driven research.Such an approach can be easily transferred to other educational, business, and management approaches.
Thirdly, this paper sheds insight into past and future research on business simulation games by analysing the most significant research trends and themes from 1973 to 2023.The following trends were identified, providing the answers to the following questions: •

What is the trend in the number of research papers and citations in business simulation games?
The SLR analysis revealed that the number of published papers increased after 2000 and is steadily developing.Although the number of published papers follows the linear trend, the growth of the published papers is steady, indicating stagnation.This conclusion is confirmed by the citation analysis, revealing that the most cited papers were published between 2000 and 2010, indicating that the research field of business simulation games is stagnating.

The paper contains several contributions.Firstly, by combining SLR and ALR, the current study analyses the research on business simulation games to solve the gaps mentioned above and provide a broader perspective on the research trends and perspectives.This paper combines computational and qualitative methodologies to identify significant study themes, examine the temporal trends of these concerns over the past several decades, and suggest possible future pathways for business simulation games research.
Secondly, the suggested data analysis framework is flexible and adaptable to various study areas.In addition to combining the SLR and ALR methods, we introduce the concept of the primary motivation in business simulation research, including learningdriven, domain-driven, and technology-driven research.Such an approach can be easily transferred to other educational, business, and management approaches.
Thirdly, this paper sheds insight into past and future research on business simulation games by analysing the most significant research trends and themes from 1973 to 2023.The following trends were identified, providing the answers to the following questions:

•
What is the trend in the number of research papers and citations in business simulation games?
The SLR analysis revealed that the number of published papers increased after 2000 and is steadily developing.Although the number of published papers follows the linear trend, the growth of the published papers is steady, indicating stagnation.This conclusion is confirmed by the citation analysis, revealing that the most cited papers were published between 2000 and 2010, indicating that the research field of business simulation games is stagnating.

•
What topics are investigated in business simulation games' research?Our analysis revealed that business simulation games investigations have two major perspectives: (i) the Learning-driven perspective that focuses on various aspects of teaching, knowledge transfer, and training in higher education and business; and (ii) the Domain-driven perspective, which refers to the domain to which business simulation game has been focused, such as decision making, enterprise resource planning, entrepreneurship, sustainability, and other issues.The most cited papers, the most frequent phrases, and the extracted topics were analysed concerning their primary research motivations.The most cited papers were mostly learning-driven, while a smaller number were domaindriven, which is not unexpected.Authors tend to cite the most often methodological papers, while narrow-focused papers are less cited [61].The most striking conclusion is that none of the most cited papers are technology driven, leading to the conclusion that the stagnation in research likely results from the stagnation in the application of new technologies in business simulation games.The ALR analysis revealed that most frequent phrases are learning driven, while domain-driven phrases occur less often.However, when the topic analysis was conducted, the situation changed, indicating that the extracted topics were mostly domain driven; however, almost the same number of topics were learning driven.

•
What is the future trend in business simulation games' research?The future trend is estimated based on the two conclusions.First, the SLR indicates the stagnation of the research in business simulation games.Second, the SLR and ALT reveal the balance between domain-driven and learning-driven research papers.Still, the technologydriven topics and phrases were not extracted, indicating that the technology used for business simulations is mature.Based on these two trends, the future of business simulation games does not seem to be on the path to breakthrough discoveries any near time, at least until new technologies, likely based on artificial intelligence [62], massive gaming [63], augmented reality [64], e-learning [65], or social media [66], are introduced in the concept of business simulation games.
This paper has several practical implications.Regarding research results that revealed three main research perspectives of business simulation games, the obtained results can be a potential guideline for higher education institutions and businesses in various industries when deciding to implement simulation games in their processes.Through the results of this work, higher education institutions can become aware of the areas in which they could use simulation games to make the learning process more interesting and effective for students of Generation Z, who require a different approach to educational methods.In the same way, the results of this research can guide practitioners from the business world to consider their business perspectives in which they could incorporate and apply simulation games to establish higher quality and more efficient firm performance.
The limitations of this work are as follows.First, only papers from the Scopus database were included in the investigation, and other databases should be included in further investigations.Second, text mining has been conducted based on the paper titles, abstracts, and keywords, while the full text of the papers could be included in future work.Additionally, to obtain deeper insights into the application of simulation games in higher education, considering the results of this study, it would be interesting to conduct a systematic review of the literature with expanded keywords in the search process that would refer to the technical perspectives of simulation game usage, supported by further qualitative or quantitative research.
