I guess I'm the only one that enjoyed single player and I have 245 hours in multi. Basically - I play this game the most out of all and I definitely do enjoy it. I also ran through MOH and Warfighter 2x and even though I recognize this for what its worth I'll probably end up preordering it because I do enjoy these games and I'm a hypocrite.
I'll be saving up if a new video card is necessary as I game at 1920x1080 and my gtx 590 doesn't run it as well as BF3. I highly doubt I'll be playing as much as BF3 as it will also be my first semester back at the university.
