Did you not hear of the backwards compatibility happening in november?

Nice,
Also your going back to school?
i just got out of school last week lol,

Also BO2 is by far the best cod probably, if not it would be COD 4/5

BO2 i would assume it has the most players because its not all Futuristic with Exo Movement, Hover,

its got nice gun balancing, it doesn't take that long to kill somebody,

and it was probably the most supported COD with competitive game types.
e.g league play, very fun to play if your Any Rank, i mean i was always Master.

but hey i quit COD, its not the same anymore.
hoping BO3 will be good when i buy it, [Only for Zombies] maybe a little bit of Multiplayer.

I am now playing CSGO on the PC, most fun i have had with a fps game for the past 2years.
