1) Online Pass.. Can't blame Dice though, that's EA, greedy bastards!
2) The new engine/graphics were pretty over-rated (graphics aren't that important to me though, I only mention it because of how much hype the engine and graphics got).
3) VERY short campaign.
4) The story reminds me A LOT of--- Dare I say it???-- Black Ops!... Kind of unoriginal....
Buying the Online Pass tomorrow, hopefully the MP lives up to the hype.
Oh, & judging by the complaints about the servers (and my history with other EA servers) I'm sure that will be my 5th complaint soon.
