No explanation necessary, use an Xbox 360 wired controller for your PC via USB port.
I have been previously using a PS2 to PC USB converter for many years to play games that require a controller on PC. I bought the Xbox 360 controller for FIFA 12 and it is the first time I have ever used a 360 controller (previously using the original Xbox controller when it was released all them years ago a handful of times).
I was hesitant at first, expressing to my friends that Sony's controller was the best for games. I now retract my statement with no remorse.
This controller is built for gaming and I purchased it for 18 pounds a year ago.
A must buy!
