Black Ops, because its not so futurist and because of Nazizombies
Black Ops and Mw2 i like both of them.
Neither. COD4 and W@W are both better, IMO.
Mw2, I own it on pc and ps3 and they both rock.
I would say Black Ops but I completed both of those games already.
I play both but I prefer Black Ops. MW2 is fun when you have everything unlocked :p
I only have Modern Warfare 2, but according to friends, Black Ops is beast for online play
I perfer MW2. Couldn't get into BO like I did with MW2.
Black ops After I started playing black ops I cant switch back to mw2 lol Black ops is to good
