I think it should be roguelike genre

You might be right, maybe I should have asked the question more clearly :D

But this is about your feelings, not objective answers. In general, that’s the point when I design a game, I think about what players should feel, not how logical or rational something is. fantasy is limitless and therefore indescribable. That’s why our approach to fantasy is based on our feelings.

I understand and, of course, I agree with you. It's just that the point of the question was something different. I want to know what is that one thing for people that defines fantasy. As for magic, it's a very broad category. However, thank you for your answer!

Do you mean things like spell casting and such? Yes, but what comes to mind when you think of fantasy?

What does this have to do with the post?
