Since Microsoft also owns Xbox, you can use pretty much all kinds of Xbox controllers on the PC unless they are wireless. I just went down to gamestop and bought one of their cheap Xbox 360 PC controllers, and I'm still using that now, even after 200+ hours of Dark Souls (as you can imagine I've thrown a few punches at it)
I'm so buying Watch Dogs when it's released. If I have the money that is.
The game looks amazing.
The drive to never give up, no matter the danger, no matter the cost.
They aren't that smart, those emulators.
