Wanted to surmise everything on the list so far. It might not be completely kosher, but I thought this deserved its own post.
1) manofthem has graciously provided a copy of Portal 2
2) AlienIsGOD has provided not one, but two copies of Nexuiz. Not only this, but you'll get a 75% discount on DLC.
3) Deus Ex: Human Revolution
4) Section 8: Prejudice
5) Worms: Reloaded
6) Battlefield 3

Wow! I didn't know the blue screen of death could get a blue screen of death.
