I never played Bioshock 2. My homie that I worked with overnights brought his xbox in with the first bioshock, and we beat it in one sitting. I really loved the first game, but heard a lot of bad news about number 2. They were made by two different development teams (Irrational Games made number 1, 2k Marin number 2.)
Infinite is made by Irrational. I am excited.
