I have to concede, Yahtzee ripped into this on the most valid points - it's treading old ground with a shred of irony, recycling some plot elements and making a couple of counter-intuitive turns, but strangely enough, I liked Bioshock 2 inspite of those points.
Granted, I wasn't all that blown away by being a Big Daddy, which kind of robbed all sense of threat and panic from the game the moment you worked out which button unleashed the BEES, at which point everything, including the metal-encased and thus bee-proof Big Daddies, would kindly stand around while I nailed them to the wall with a handful of steel harpoons.
In short, good review, although I was a bit worried when the first criticisms came down, things were nailed on the head without wasting time bitching about the minutia.
