I pre-ordered from TTG and they sent me a Steam key and I'm new to Steam. I downloaded it and it runs, but I don't have a usb mouse. I have a "Power A" usb controller, which is meant for the computer and PlayStation 3 system. It registers, but it's configured horribly. The game registers it as an Xbox controller, and I've only found about three buttons that actually work; the "R1" button registers as the "A" button, Start is the same but lags, and the triangle button registers as "B". If anyone can help, it would be greatly appreciated.
