I still haven't gotten around to playing BioShock, though it looks pretty good. A few months ago (over a year ago?) I posted how I really wanted to see a steam punk game handled by a Western developer the right way. I really wanted an RPG, but I guess I may have to settle for this (BioShock doesn't have enough RPG elements to really light my fire).
@Nels I assume since you're here that we probably have similar taste in games. I'm not a FPS fan by any means at all whatsoever, but I really liked Bioshock despite the lack of RPG elements (of which, you're right, there are few).
