Bioshock 2 will be for me, not because it was a bad game but because it could not live up to the original.
I remember playing the first hour of the game thinking "this is just a carbon copy, this adds nothing new".
The multiplayer was a fun distraction for a weekend, I am not against games adding multiplayer but again, considering how fresh the first game felt even the multiplayer in number 2 just felt like it borrowed too heavily from Shadowrun and Team Fortress
