I get why some consider this to be the worst of the trilogy. We've already been to Rapture. What else is there to tell? However, this expectation ends up working in the game's favor. The gameplay is better with a less intrusive hacking minigame, upgradable plasmids, and more decisions to consider with the little sisters. Top that off with a deeply personal story and a DLC that is among the best in video games, and BioShock 2 ends up being an improvement over its predecessor.
