Oh and gunsmith on Ghost Recon

Bad: Cannot be used in a small room, still yet to release that killer game.

Good review, if you've played Joy Ride, the response of this game when in the kinect mode is ten times better. The voice commands are great too, it quickly picks up your voice and you can jump to community, my cars etc etc.
The kinect driving games are pretty much "arcade mode". Take it from me don't do nurburgring in kinect mode.
