It's such a good game. Now that the Vietnam expansion is out, it'll be even better. If you don't like generic FPS's like CoD, i'd recommend it. I just picked up the Deus Ex pack as well as the Prince of Persia: The Forgotten Sands deluxe edition for $10!
If your looking for a generic FPS dont buy either MW:2 or Blackops imo, COD4 was a better standard fps than both, more fun, more balanced, better maps. Just better. imo ofc.
Badcompany 2 is a lot of fun also, though it is a game that gets significantly more fun if you have a group of mates to play with, its a game that really rewards communication, even more so than COD/CS.
