Outside of the terrible hosting issues which plague COD Black Ops I think it is the best mulitplayer version to date. I love the unstackable killstreaks as Lash mentioned, I like the perks, and all of the guns. The one thing I hate about the whole COD series is how often they pump out new games. This makes the games have no longstanding worth. Each game is only valuable for a year until the next game comes out. With this rush to put out games annually I fear that the quality is compromised. I hate to turn this into a socom thread but I loved that socom games were the tops of the market at the their time because of the quality in each game. Outside of Confrontation which isn't a true socom game because it wasn't Zipper and didn't have single player, each socom game was a huge improvement on the last. In the last 4 COD games I have seen little changes made to the franchise.
