Must Haves: Gears of War 1 and 2
Halo 3, ODST, and Reach
Alan Wake
Forza 3
Fable 2 and 3
Also some stuff you should think about getting are Kinect Adventure, Kinect Sports, and Dance Central. All great fun especially with a room full of friends. Also Xbox Live Arcade is filled with tons of awesome gems.
