The single player campaign is great has alot of great scenes, and cities you can go through, with a good story.
Not so much the Online Multiplayer. Has quite a bit of lag and accuracy has much to be left desired. Possibly due to lag however I noticed ALOT and I mean ALOT of shooting non-moving targets at close to semi-close range and have emptied clips to have not hurt an opponent. Never had this issue with other COD. Activision took a crap on Multiplayer shooting experience. My advance buy the game if you like the campaigns, but stick with COD MW2 if you like more accurate game play.
