Now, I've seen people try very hard to draw intricate, and sometimes senseless connections between Rapture's Bioshock games and the new one in Columbia. The connections are few, and mostly not direct. The few direct connections include; Fink seeing Rapture technology through a tear, turning plasmids into vigors, and big daddies into handymen. There are no connections between the characters, as the games take place several decades apart. However, there is the theme, there is always a man, always *a lighthouse, always a city. This implies that Rapture only exists in timelines where Columbia never existed. Not failed. never existed. Because the mistake was never made, and if Comstock didn't teach the world how foolish the idea of an isolated Utopia was, Ryan would not think twice about the grandeur of his dream.
