For some PC gamers, the ability to use an Xbox 360 controller was a viable alternative to the mouse and keyboard setup. But with the announcement of the Xbox One, and subsequently an entirely new controller, questions lingered about compatibility. Thankfully, a Kotaku interview with Microsoft has confirmed the Xbox One controller will work with PC titles--eventually.
Currently, the Xbox 360 controller works with a vast array of PC titles that offer gamepad functionality. The controllers are also compatible with some Mac games, using third-party drivers.
