Same game w/ a different coat of paint on Black Ops. It's also got that stuck-up feel of "ZOMG the game b4 us wuz the behst thing in Entertainment EVA!!! LOOK AT ME!!! I'M SO ****** TOOO! LOVE ME ACTIVISION LOVE ME!!!" from Treyarch with that game.
I've stated this before so I'll say it again - MW3 better do some long-needed innovation.
oh yea, MW2's better due to the superior developers who don't leech on other's success; and it has Spec Ops. Cooperative gameplay FTW!!!
Black Ops. It took everything that MW2 did right, fixed what MW2 did wrong, and added a lot of nice gameplay elements. MW2 lacked any form of balance, and quick scoping way way, way, way, way to easy.
MW2. Black ops is more belanced, but that takes a lot of fun out. Sniping on black ops is weird, you get a one shot kill zone that is way to big. The smg's feel weird (might just be because I play on a different platform). I would take zombies over Spec ops, so that is where BO beats MW2.
Black ops has a weird story, boring multiplayer maps and a lot of campers. Mw2 has to easy Qscoping on Consoles and is sometimes unbalanced but i chose MW2 over Black ops
