[quote name='Dark Rider']I already played the first one. Is this worth it for the second and add ons?[/QUOTE]
If you've only played the first one, and you liked the first one enough, but never got around to the second one, then yes. Controls for Bioshock 2 are a lot better and more intuitive. Basically the same game, but with a few updates. Either way, story's pretty cool.
