Bioshock 2 is awesome!
Bioshock 2 is better to play and the story is the most emotional I have seen on a game.
I was in tears for most of it the first time I played it.
But I think Bioshock 1 is longer or feels longer.
Also BS1 is better in that you can backtrack.
Also nothing will ever top the first time you see Rapture.
The first time you see Bioshock it is like wow......
I think it is better in many ways than Bioshock 1.
