Are there any FPS games out there with full gamepad support, or do they all require playing with a keyboard (or using software to map keyboard commands to a controller)? FamiBox
Yes - they're on the 360 and PS3 :)
If you look for PC games with the Games For Windows logo across the top they are meant to fully support the 360 pad. The only one I can think of right now is Supreme Commander, but that is an RTS game.
I can't think why you would want to use thumbsticks instead of a mouse, but I guess I'm wanting the same thing from my 360 - to play FPS on it with keyboard and mouse.
