Hello everyone! I'm writing research on topic - "The best game engine for a small team to create 2D indie games". I need a research consultant or any feedback in this topic because I can't do it on my own - I'm not a scientist or someone else in game engines and other things. I've chosen criteria and game engines for research. They are in image "table.png" below. As we can see, it contains 6 game engines and 10 criteria. I want to know - are this criteria and game engines suitable for my research? In "Notes" section I put quiestion to help respondents answering.

In the last line - Value of criteria(in different words, multiplier), I wrote my own estimation of each criterion. This method let us to get different order of engines for every game development team. For example, if I value "Learning Curve" and "Ease of use" I will get one order, but if I value "Genre" and "Extra Benefits" I will get another order. Thank you for your attention. I hope you will leave feedback. Have a nice day :3.

Thank you for your answer. I can't deny that it's school research, but every research needs a research consultant  - expert in researching theme. Our school doesn't have any game programmers and so on х). I know that no one will spend a big amount of time on my research, then I need at least feedback on this forum. I made theoretical part, but if I want get qualitative results, I need an assesment from master's point of view on my criteria. Thank you?

I've uploaded all polls. Please participate in them. Make lives of beginners indie game developers great again! Thank you.

The poll looks quite useless. I have no answers (don't use any game engine), but there is no single "best" like you seem to believe, they are all the best choice, for their users.

You still ask many questions that you can easily look up yourself, and you ask about properties that apparently are relevant for "best", but may be totally irrelevant to a user.

Yes. I will redo this poll. Maybe i will ask professionals about pros and cons in each game engine, then i will create a table as a result. How do you think, will this method be better?
