mw2... because it has better graphics and its always fun and is not as bad as black ops ..... but by far the best cod would be cod 4 modern warfare.... its simple and fun
Black Ops has the most sold
call of duty black ops is better casue they have a zombie game in it
If you feel newer is always better then Call of Duty Black Ops will be until Call of Duty Modern Warfare 3 is released late this year
Pong
call of duty
Call of duty modern warfare 2 because the game had more sale and was more wanted then black ops yea mw2 is the best better graphix better guns better maps but blaco ops has zombies so if mw2 had zombies it would be too good for life
Call of Duty: Black ops is a great game if you like first person shooter games. But, I think Call of Duty Modern Warfare 2 is slightly better. It all depends on your opinion.
Call of Duty Black Ops
Call Of Duty Black Ops, I Think Its Better Because You Get To Create Your Wepon Online, But If You Like Assasains Creed, Or Stuff Like That, Uncharted 3 Is The Game For You.Uncharted 3= best game EVER!
no i hate both of them stick with a better game bud
Very!! its better than any call of duty game try it! Well except the new Black Ops game! That's the Best!
yes ! The full title of the game is Call of Duty Black Ops and it was developed by Treyarch who also developed the games Call of Duty 3 and Call of Duty World at War. The are working on a new Call of Duty game to be released in November 2012
