Microsoft's Major Nelson has revealed the top Xbox games of 2011, based on unique global users logged into Xbox Live. These aren't representative of top games sold, as they don't cover people who play offline, but the numbers are fascinating nonetheless. You may or may not be surprised to see the Call of Duty games took the top three spots, despite only one of them being released this year. Overall, the list contains five games in the series, which is sort of incredible. Here's the list:
1. Call of Duty: Black Ops
2. Call of Duty: Modern Warfare 3
3. Modern Warfare 2
4. Halo: Reach
5. Battlefield 3
6. Skyrim
7. Gears of War 3
8. FIFA 12
9. FIFA Soccer 11
10. Madden NFL 12
11. GTA IV
12. NBA 2K11
13. Battlefield: Bad Company 2
