Ahh umm stay away racing games with a controller
Ahh umm stay away racing games with a controller, racing does not go well with a standard keypad controller
Only reason I'd use a controller would be if I had a laptop and didn't want/couldnt' use a mouse!
Call of Juarez and L4D works from what I've tested with the 360 controller, but COD4 MW doesn't - Natively anyhow.
So you'd not play a racing game with a controller but you'd play a game like L4D with one?.......
