Simple answer: You don't.
Less simple answer: Don't create a game with the outlook of "let's take what people like and make a game out of it". Start out with an idea, preferably new or interesting but it must be something that you have a passion for. If I make a game it will probably be an rpg because I like rpgs. I won't work on an FPS. Don't try to please gamers because you can't please all of them anyway. Work on something you like and hope that others do as well.
