I've finished Bioshock (and loved it).
I played through with rescuing all little sisters first, then went back and harvested the 3 just before the proving grounds to see the other ending.
I may go see Sander Cohen's apartment.
Is there anything else worth doing before I uninstall?
I was surprised to find the game was really finished, because the Bathysphere destination choice screen had 3 or so gaps when I saw it last (am I maybe missing some areas?)
(I have to uninstall, I'm low on HDD space and want to play the next game).
