Bioshock was a blockbuster success with its intense atmosphere and thrilling story about an undersea utopian society gone awry, with all the loose ends wrapped up neatly in what was (at the time) a stand-alone game. Not surprisingly, popularity and money gave the game what I like to call a case of the sequels. Bioshock 2 adds multiplayer and builds the mythos of Rapture, but the slow story and degraded graphics make it inferior to the original.
