From all the internet chattering, you would think BioShock is the bestest best single player FPS ever made (Most game rating sites gave it like 9.99999/10). I played the Xbox360 demo and thought it was indeed very well made with incredible art and voice acting. The atmosphere is pretty creepy too. So if you wanted to see what all the hype is about.
