Bioshock goes above and beyond the call of most first person shooters. The game is not only a great shooter, it is also has a great story, has great gameplay mechanics (upgrades, etc), and has a great interface. The game's story is very unique and really pulls the player in. The game has MANY ways to upgrade your character, from new weapons to weapon upgrades to tonics to extra plasmids and beyond. The enemies in the game are unique and well-designed and the Big Daddies with the little girls make for an emotional twist to blowing things up. If you enjoy shooters or a great story this one is for you. I highly recommend and can't wait to play the sequel.
