But if you want to play it with a 360 gamepad, perhaps you have a 360, and if so, you might try checking it out on Xbox360. It really plays quite well now and is obviously optimized for playing with a 360 controller.
I have a 360 pad but no 360... it's a good dedicated controller for the PC as well, and most PC games that play better with a controller support it natively, rather than needing setup.
And even if the 360 port is improved this time around I'm sure the PC version is still the better of the two.
