My buddy and I are still waiting for the prices to drop on 
Army of Two: Devil's Cartel and 
Gow: Judgment, so I decided to check XBox Live activity just to see how popular they are.

The short answer is, they're not, but the results are surprising.
- Four 
COD titles in the top twelve, in order of release. Number 12 is 
MW2, which came out 2009.
- I didn't think 
Halo 4 would be as low as it is. I'm sure it'll be back up once Spartan Ops is back on. 
Halo: Reach is still number 14.
- The number two title is 
Minecraft?
- 
Gears of War 3, which came out in 2011, is sixteen.
 Gears of War: Judgment, which came out in March, is out of the top twenty. Ouch. 
- 
GTA IV, which came out in 2008, is still number nine. Wow.
