I call blasphemy! The only real differences are when devs add controls that other games wouldn't have, and I've never had a that you couldn't remap them if you didn't like the control scheme, something you normally can't do on consoles. I also like being able to pick what I want to game with
keyboard and mouse, or if I'm feeling optimistic, gamepad. And for the flight sims, a good ol' joystick.
