Scrum VR: Virtual Reality Serious Video Game to Learn Scrum
Round 1
Reviewer 1 Report
I have read manuscript with great attention and interest. The article deals with a topic of education system for software engineering. The application is interesting and I think that the article can be accepted after minor revision. In general, you have a proper academic way of referring and a good language. I really like the introduction and state of the art sections.
Congratulations to the authors of the work.
Comments and suggestions:
1. Why did you choose Unity engine? Are there any alternatives?
2. What are the main limitations of your education system?
After revision, the article can be accepted.

Dear reviewer, thank you for your contributions to the article. I am responding below with the solution provided to each of your comments.
1.-Why did you choose Unity engine? Are there any alternatives?
We have added this reference comparing Unity and unreal for developing educational tools: Dickson, P.E.; Block, J.E.; Echevarria, G.N.; Keenan, K.C. An Experience-Based Comparison of Unity and Unreal for a Stand-Alone3D Game Development Course (2017).
The main reason to use Unity is because of its simplicity when developing applications with low resources (this is ideal for the development of a mobile application).
2. What are the main limitations of your education system?
It is now explained in the article:
"The most notable limitation is referring to the cybersickness problem. Although locomotion techniques are used to minimize this problem as presented above, it is very difficult to eliminate it completely. In the case of Scrum VR, none of the users reported getting dizzy, but some did experience slight discomfort."
Best regards
Reviewer 2 Report
In this article, the authors present a Scrum VR system as an effective learning method. The idea is new and the implementation is clearly described. The evaluation of the performance is carried out in university for students and teachers, and the developed video game seems fulfill the purposes.
First of all, it is a well-written paper and has interesting idea shown to the researchers in this field. Second, it provides the system development description and suitable demo. Third, as the related applications gradually moves from VR to AR for better interaction, the authors should refer to the work "Human Computer Interaction Using Face and Gesture Recognition," APSIPA Annual Summit and Conference, to discuss the possibility of the extension to include the human interaction in the future. Fourth, it is not common to use "chapters" to divide the content of a paper (page 4). The authors might consider to make some changes.

The reference provided has been added as indicated in the section of the future lines.
4.- It is not common to use "chapters" to divide the content of a paper (page 4). The authors might consider to make some changes.
This was a mistake on our part, perhaps it was not clear that we were referring to the content explained within the virtual experience. It is divided into chapters as they are different parts of the virtual game.
In the article, this part has been clarified.
Best regards
