youre probly very yougn when you still enjoy COD i only liked 4 btw i put in BO yesterday and got a 6 kill streak and then killed with a guy making a 180 turn with half a clip in his spine. its a crappy game spend you money on something refreshing like uncharted 3 Batman:Arkham City. Skyrim. those are the games for the badasses.
The reason they complain is because BF3 is gonna be better than MW3 due to the competition many people vote on. They think BF3 is gonna be better because: It's gonna have Vehiciles and you play as a small part in the story.
MW3: You play as the big hero, They are resurrecting Zombies except with real people and killstreaks, and they are also resurrecting Special ops.
