I liked Bioshock. I never finished it, but it was a good game with a good story.  It teeters on the edge of action and survivor horror.  The environment is very creepy.  The only thing more creepy than the environment are the residents of Rapture.  Bioshock 2 should be upon us soon and the creative director was kind enough to walk through the first 9 minutes.  Check it out.  Looks like I’ll be buying this one too.
