The first CODs were good for the PS2. I still enjoyed MW and MW2 for the PS3, perhaps because they were the first CODs for the 7th generation. MW had great impact, it was the first, MW2 had a nice evolution and new features, but from there on they pretty much never added anything. And a confession, I actually liked black ops, the multiplayer kept me busy for a very long time
