Bioshock is a game that mixes the best of First Person Shooters and Role Playing games, and will tell you by the end if you are Mother Theresa or Spencer Pratt (IE, useless douchebag)

Just The Facts

  1. Bioshock takes place in the 1960s, after a plane crash leaves you stranded in the mid-Atlantic.
  2. You end up in an underwater dity called Rapture, run by dirty Objectivists.
  3. You survive by injecting yourself with Plasmids; genetic modifications that turn you into Jesus, if he were crossed with Gandalf and an electricity-spewing flamethrower.

Cracked on Bioshock

Bioshock starts in an airplane and winds up under water. You go to Rapture, an underwater city built on the principles of Ayn Rand's Objectivist philosophy, and shows how fucking nutty people go when they get to do whatever the hell they feel like doing.

By the time you show up, the whole ecity is falling apart and is run by a crazy asshole named Andrew Ryan. Ryan originally concieved Rapture as a place where people could live out their full potential without having to worry about morality and other minor shit like that. When people turn out to be fuck ups because, well, they are people, Ryan loses his shit. By the time you arrive, so has everyone else.
