An excellent look into a Utopian society that quickly degrades into a dystopia.
Although the game does contain SecuROM I had no trouble installing and playing it. It has been a while since a game has made me think of different ways to solve problems or fight enemies just for the simple fact that there isn't a ton of ammo/health kits/eve kits laying around to make it a true FPS.
All in all though I would say that BioShock is a great game, and its probably one of the best that I've played in quite a while. I encourage all who own a PC that is good enough to run it to pick this game up, its got a little bit of everything, and everyone should find something they like in it.
