i honestly think that black ops has a lot of amazing ideas and features in it that make it a great game. Removing stopping power was the best thing to ever happen for the call of duty series. However like everybody has been saying, the engine for it is VERY bad. I personally enjoy black ops a lot and think it's a super fun game. I just think some work needs to be done on it to make it better.
I honestly was not a fan of WAW at all purely because i hated the vehicles in the multiplayer. This honestly was a game changer for me.
MW2 is a really bad game in my opinion, (commando, one man army noob tubes, danger close, the list goes on and on), but the thing that made me play this game pretty much every day was the modding. The modding in this game was something truly special and something that will always remain as one of my best video game experiences ever. The amount of thought and work that went into Patch files for JTAGS to be used on MW2 was honestly staggering. If any of you people ever got into a modded lobby, you know what i mean. When Microsoft essentially blocked JTAGS with their latest dashboard update, i almost wanted to cry. You could compare it to getting C-Blocked by Microsoft.
