Haha my gf said the same thing. Alas I don't get to play that much and doubt I've improved that much at fps. Whilst I like multiplayer, I hardly think the $100 pricetag is justified considering it's essentially just a couple of new maps. If the singleplayer mode is gonna be so shit then just release a dlc map pack. Obviously it wouldn't sell as much as a 'whole new game'. They've worked their way into a great business model. Sorry for my nonsensical ramblings. I'm just frustrated at a franchise I've supported or nearly a decade when their primary product was a single player fps.
May be $100 where you're at, but it's only $60 here, unless you want the $100 "Elite" edition, which I couldn't give two-shits less about. lol. The new game does have some cool new changes to multiplayer... nothing too drastic, but it seems like they tried to balance the game a bit more. That's just my opinion though. I also think it's cool to get new Special Ops missions and such.
I'm finding there is a major divide amongst the community though.... it seems that those that loved MW2 hated Black ops, and those that loved Black Ops hated MW2 and somewhat enjoy MW3. I'm in the latter category--I hated MW2, but played the hell out of Black Ops and love it. I hated the BlOps campaign, but multiplayer was fun as hell. I mean c'mon, who doesn't like getting a sick kill from across the map with a tomahawk ricochet?!? or an exploding crossbow arrow to the forehead?
