I have to add my two cents. I have Black Ops 2 but didn't buy the first Black Ops. I have been a long time COD player and couldnt deal with the same game wrapped up as something new for $60. I purchased the new one mainly for the Zombie mode. My wife loves to sit there with me and murder hundreds of the walking dead.
I think the multiplayer has improved and the campaign is pretty good. I would recommend it but if there was a new Battlefield out I never would have looked at Black Ops 2.
For what its worth I also picked up the Need for Speed Most Wanted and absolutly love that game. Found the Challenger and Viper in the first 5 mins and spent the night cruising around the city. I will admit I didn't stick with the Challenger long. I found the GTR and started drifting.
