Well, I played Battlefield BC1 and the multiplayer game gave me constipation... and that's how I feel about the Battlefield series.
The graphics and game play are beautiful, and they always have been, but certain things bother me.
Any online game where you have to shoot a person more than once in the head to kill them...no.
I HATE shooting half a clip in a person and then they manage to skip off like nothing happened while I'm taking an hour to reload my gun.
Spawning in front of the business-end of an enemy tank repeatedly...not cool.
Since I have a hunger for those types of games, I think I'll pick up Bad Company 2 today and see what pisses me off about it.
