I kept my expectations to a reasonable level for this game, as I have been disapointed in the past. However, I thought it was a very good game. I liked how there are tons of new modes for multiplayer, along with variations on old ones. Deeper customization is also a plus. However certain things did irk me, like how Bungie STILL didn't fix the friendly A.I., I got stuck a few times because they wouldn't do what I want them to do. Also, the multiplayer spawns don't seem to work right, especially during objective games.
Overall, I thought the game was really good and I hope the community on there remains strong even after Black Ops releases.
