I really do.
Netcode is miles better than MW3 and BO2. I've had a couple of dodgy games but that's it.
While the maps are maybe a bit too big for 12 players they are excellent(for the most part).
New game modes are fun. I especially like Cranked.
I'm not saying this game is perfect. Snipers are well OP and just too easy to use. Insta-death is annoying.
I don't like that the point streak system seems to favour people who run around killing rather than objective players - I play KC and you only get a point towards your streak for getting a kill! Confirming or denying a kill does nothing.
BUT this game has only been out a couple of days. A bit of tweaking from IW could make it my favourite COD since MW2.
I wonder how long before people come in with the usual "This game sucks! You suck!" comments...
