When I booted up Call of Duty: Modern Warfare 3 on my PC to play with my wife, I 100% knew that it would give me trouble when connecting my Xbox controller.
I don't know what it is about controllers and PC, but anything that isn't Steam has a hard time working with controllers. This might have something to do with Steam prioritizing controller-use, but that wasn't the case here despite me playing on Battle.net.
