There is this short essay written by argentinean author Jorge Luis Borges where he tells that mankind storytelling has always been the same four stories retold in a inifinite number of ways but are the same four in essence. And we are doomed to keep retelling them. I think that's kind of what Levine&staff did with bioshock. Bioshock Infinite is both a retelling of the original story and a justification of why it has to be so . It's like they are trying to say "Look there is this story,about a man that built a tower to achieve his dream,his sins stained the foundations tough, and it falls on his sucessor to both finish it and cleanse him.And that's how it always is."
