Just finished Bioshock, with the "good" ending. No spoilers here -- play the game if you haven't! It's got a great thematic consistency you don't see in most games, and is far better experienced fresh than hearing about some of the sequences beforehand.
Not sure if I will reload a save to dig up the last few logs & weapon upgrades I need for Achievements. Perhaps after this holiday's amazing rush clears out I will do a second playthrough on Hard and really go for 1000/1000.
Just in time for me to dive into Metroid Prime 3...
