I am a big fan of the keyboard controls, and as far as I know you could just play with a keyboard rather than the Xbox360 controller.

The graphics are about the same as PC, but I can tweak the registry settings on PC to make it look a hell of a lot better. As well as things like draw distance to match up to the Xbox360.

But, other than that, it's pretty much the same I'd figure. Except, if you have HDTV and all that mumbo jumbo, you might find it's better for you.
