Just wondering... mine would be either WAW or MW2
My Bad I don't like mw3 and black ops 2 is fun but it's kinda weak and gets boring quickly the zombies is weird even though I've played them numerous times

MW2 through MW3 for MM. It started falling apart at Bl Ops II. Finished off by Ghosts. CoD2 and WaW, MW had the best campaigns.
