I personallt prefer Bioshock 1 over 2. More memorable stages (Arcadia, Fort Frolic), plus I found Andrew Ryan to have much more of a presence than Sofia Lamb, I didnt find Bioshock 2 truly something great until the last part of the game, it felt too much like a recreation of the first game, especially the very beginning. I also wonder that since Bioshock 1 had a city underwater and Infinite had a city in the sky, would the next one have a city underground?
