Yeesh. No responses for Bioshock 2? Sad...
At first I didn't know how to feel about the game. It definitely lives in the shadow of the impact of the original, but it's one of those games that's actually grown on me
since I beat it, and it actually keeps me thinking about it long after, particularly the differing messages in the ending. One claims that "innocence is a phase meant to end," while the other challenges that with "[Sofia Lamb] believed this world was irredeemable, but in forgiving, we leave the door open for her." Definitely some food for thought there, IMO.
Anyway,
Penny Arcade pretty well described my initial feelings on it.
