The best COD series has to be Black Ops, mainly because it is the most uniqe and it has more of a story than any other one. Now if you are watching or watched the Blsck Ops 2 Gameplay yu should know that it is completely freakin sweet. Now the most dissapointing one has to be Modern Warefare. Just because of Mordern Warfare 2 and 3 were just sooo disapointing. Why you ask, it is just because the gameplay. Like just what happened to Soap and stuff, and just what happened at the start of the game. I think that they went a little overboard. And at the start of Modern Warfare 3 why did it have to be in New York City?
