I think we can all agree that CoD started to get old around MW2. CoD4 brought a lot of crazy shit to the table, a lot of which people thought were innovative and ground breaking. But MW2 was the exact same thing. Except that things were so broken and there were so many glitches that took forever to get fixed (Danger Close+Grenade Launcher+Scavenger/OME= OP as FUCK(Care Package glitches, Javelin glitches)). Most people only played for WaW because of zombies. The single player campaigns are ok, but they're just bland after about the first five minutes. Go here, shoot generic bad guys, get shot, play with a vehicle for about 5 minutes, or a level focused on just the vehicle, shoot more generic bad guys, PLOT TWIST, shoot last group of bad guys, end. Black Ops 1 was pretty good, but MW3 was just a god awful excuse for a game. Black Ops 2 had some new stuff that the first Black Ops didn't, but honestly its just the same thing..
