I'm definately going to be playing this game for months to come. There's so much in it.
Multiplayer, zombies, wager matches, single player and the whole game economy thing...not forgetting the theatre mode for those special moments that we all have (and in MW2 were lost forever.)
Even forgot to mention combat training!!!!
OK so 2 days in and the servers aren't perfect yet but its been better today than yesterday.
I played MW2 alot (all online) and WAW and this game just moves the gameplay element to the next level. I love it.
