I found MW2 multiplayer to be good right up until I got Battlefield: Bad Company 2, at which point MW2 MP just seemed quite bland to me. Even though it has less modes, BFBC2 MP I just felt more excitement in, and ion fact its probably the game I've done the most MP in and enjoyed the MP in the most. MW2 campaign was good, and I've been tempted to play some levels again, but at the same time I have been tempted a couple of times to trade it in as well.
I've played a few games in Clone Wars: Adventures this week when taking breaks from my massive assignment, but I haven't had much time to do any proper gaming (CW: A is just a bunch of mini-games). Hopefully that'll change next week as I'm looking to get myself Apache: Air Assault as, thanks to an Amazon voucher, its come within my "I'll definitely consider buying" price range.
