A game is a form of art. If you create only what others ask of you then the result will lack the passion it deserves and be a lesser form of what it could be. I couldn't care less about the mechanics but I'd rather those be pursued then end up with something lacking heart.
It's your creation and your time and energy being expended, not the players. See to it that you get as much pleasure in creating the game as players do exploring it. In other words, do what you want, and haters can go fuck themselves.
