What with Steam's Big Picture mode launching, and gamepad support becoming more and more common (or even the preferred control scheme) with PC Ports, I was thinking it's about time I jump on the gamepad-on-PC-version bandwagon, especially since XCOM: Enemy Unknown's (the enemies are aliens) keyboard and mouse support seems a bit unrefined from the demo (which for all I know could be fixed by launch), and I'd like to try the gamepad support out for it.
My problem is that I do not own an Xbox 360, let alone a 360 controller. I do, however have a PS3, and a PS3 controller. I'm aware of the fact that 360 controllers are compatible Steam gamepads, but I have no idea how to get a PS3 controller to work, or if it's even possible. So my question to YOU duders is thus; Can I use a PS3 controller as a gamepad on my PS3, will I need any extra stuff or can I plug the USB charger straight into my computer, and how do I get Steam/my PC to recognize it? I'm using Windows Vista (Yes, I know. Trust me, I'm not happy about it either.), if that helps.
