As close to the perfect game you as you can get. The story line is very strong, compelling, sucks you from Ryan's speech in the bathosphere to the final cut scene.
Amazing storyline, great combat system, immersive gameplay, beautiful and breathtaking locations, one of the best and most shocking endings I've seen Cons: No multiplayer (made up for in Bioshock 2 though)
This game is the total package. Great graphics, in-depth game mechanics, dark foreboding environment. Quite possibly the best thing to happen as a result of "Atlas Shrugged". Cons: Loses it's challenge when you're decked out with plasmids and custom weapons. Especially during the endgame boss.
