Beautiful and fun - why can't I find a woman like that?
The choices and character building in the game really make you feel the need to try lots of different things. At times the choices can slow the game play a bit but that's the trade off for a game that doesn't force an identical experience on every player.
If you're looking for a balls to the wall action game, Bioshock is not going to be for you. The focus is far more on story than on big explosions and killing bad guys. It's a compelling storyline that really has you on the edge of your seat and has some excellent plot twists.
As for the tech glitches some have had, my system runs Bioshock perfectly at 2560x1600 and all the eye candy on. However, I'm still on XP so I can't speak for Vista.
Bioshock isn't perfect but I promise you, this is not the last in a new type of game - the RPFPS (Role Playing First Person Shooter). Games like this one and Vampire a couple of years ago are laying the ground work for a whole new type of interactive entertainment.
