If you're going to set up a fiction for an intelligent game series, then basically ask Ken Levine and Irrational how to do it.
Their series of "Columbia: A Modern Day Icarus?" videos is a brilliantly realised piece of spoofed 'Documentary' making. Not only watchable, but believable and very, very spooky too. Let's hope the game, Bioshock Infinite that is, is near half as good.
