Played the steam version of the game with an Xbox controller, mouse and keyboard never work for me. Not a bad game but I don't think its the best FPS I've played. Certainly Half-Life kept me more interested in the story, but Bioshock did have the better environment. Fort Frolic was the high point for me, though the Point Prometheus level had a nice creepy vibe to it. In terms of gameplay, I really enjoyed it. Lots of environmental interactions and different ways to approach the fights. I spent a lot of time hacking the various security systems available and letting them do the fighting for me. At one point I had a veritable army of drones following me. Overall, a definite recommend.
