Better yet, they can check their computer inventory (how much the computer says they have) compared to what they actually have. Since the computer says they sold one but they actually didnt give you the disk, they will find an extra disk in their possession.

In no particular order:

1. Mercenaries II (Hells Yeah!)

2. Fable II

3. Gearas of War II

4. Star Wars: Force Unleashed

5. Unreal Tournament III

6. Resident Evil 5

7. Splinter Cell: Conviction

8. Tom Clancy's End War

9. Huxley

10. (They say they are working on it) Dead Rising II

Looks like mostly sequels, but def my favorite games in past and the ones I most look forward to.
