Which is better?

Both of them.

Buy both. Amazing games that shouldn't be missed out on.

They're both pretty good.

You can get both of those plus Spec Ops: The Line for $9.99 from Amazon.

They may also do the bundle just for the Bioshock games and that's only $5.

The reasonable option would be play the first and then after you completed it, go try the second one.

The first one. I only have the 2nd one on PS3 and i don't understand NOTHING about the story. Still, Bioshock 2 is a pretty fun game.

Both of them, only five dollars on amazon.

They're both good games but I really feel like 1 was a better game. I think a lot of that is because the world is still new to you though. I honestly feel that Bioshock shouldn't have made a sequel because it kind of ruins the artistry and story for me.
