@Oberael, I thought this was common knowledge, the Bioshock series is based on Ayn Rands philosophical beliefs, especially those in Atlas Shrugged, It doesnt take an English major to figure out that the name Andrew Ryan is practically an anagram of Ayn Rand.
Read her literature, its very beneficial, Comparing her beliefs to those Rapture is founded on is interesting too.
Funny tidbit, in the book We the Living (obviously by Ayn Rand) The word "Enraptured" Is about three sentences in on the first page. Wonder where the got the name rapture from.....
