Aim assist on pc games?

I have an xbox 360 controller for my pc (mainly for action/adventure games). I recently played crisis 2 with it, and noticed how fun it was to simply recline in my chair and have the controller lock on to the enemy. Don't get me wrong, a mouse and a keyboard would crush a controller any day, I know this. I want to know if anyone knows of any other pc games that utilize the xbox 360 aim assist?
