Probably about 8-10 hours in one week, alternating between:

Call of Duty 4 (360)

Halo 3 (360)

Diablo II (PC)

Rock Band (360)

NBA 2K8 (360)

The Payne Series was amazing and im sure there is going to be a third one, especially with the movie coming out. I think the movie is a way to promote the next release.
