BioShock didn't need a sequel.
I know it, you know it; heck, I'd bet if they were being totally honest, the staff of 2K Marin would tell you they knew it too. BioShock was that rare combination of a perfectly realized world, fresh yet refined action and a narrative that left me with no real burning questions. It didn't need a sequel.

But all that has very little to do with BioShock 2 because whether it needed to be made or not, it's here now. And the surprise isn't that someone other than Irrational had the chutzpah to make a BioShock sequel. The surprise is just how worthwhile it is.
