Ha! You're showing your age now, I was a Q A O P space guy back on the old ZX Spectrum. It's WASD all for the left hand now, mouse in the right hand. Space bar is still used for jumping though.Q, A, O, P and Space for me...
Unless I'm playing a modern AAA game that's not an FPS, then it's got to be a controller, surely?!
We have to remember that most of the games are optimised for console play these days and with that, the controller as the input device.
But no, all modern and AAA games can be played very well on mouse and keyboard unless it's a 2D fighter like Mortal Kombat, Tekken, Streetfigher, etc.
