What a coincidence - I am just getting ready to start AC:Revelations. I decided to get an XBox controller for my PC. I have always had a few annoying issues with keyboard/mouse control and have read that with Revelations, mouse sensitivity has been an issue for some players. We'll see how long it takes for me to get used to it. The controller just arrived today from Amazon, so I'm anxious to get rolling after the kids are in bed tonight.
