Alrighty, I've finally got a 360 w/ kinect so I need some games to play. We got a couple of the Kinect games to go with it, but I want to get a few "serious" games. So, what are some older (cheaper) games that are X-box exclusives (I have a PS3) that I need to check out? I know, I know... Halo... but I'm not a huge FPS fan... so lets see what you guys have to suggest. Thanks for any input.
