Did anyone think they were trying to make a point that choice in the game doens't really matter, you'll still reach the same conclusion?
heads or tails... doesn't matter
presenter or couple, they still see your hand.
you can kill slate... but if you don't comstock is going to do it anyway.
Bird or cage.. either way Liz is still kind of boned.
Baptise or don't get baptised... there's still a comstock and still a dewitt. IDK.
That and when you (booker) say you won't give up baby Anna during the ending, Liz says "we'll be here until you do".
It's really echoing Bioshock's "illusion of choice" scheme. AFAIK, none of the choices matter at all except for dialogue lines from Liz or other NPCs.
He either remains Booker, has and eventually sells Anna, or he becomes Comstock and forms a mega-cult in the sky. All that hinges on one simple choice. Albeit a choice the gamer doesn't have any control over.
True, but technically, to sell Anna, Comstock must be present. If Comstock has no chance to enter existence from the baptism 'choice' disappearing from the universe, Booker has much less of an opportunity to sell Anna.
I think it could be a possibility for hope, or as someone mentioned earlier, an inception style "decipher it how you will".
But the real beauty comes from starting a new game, and realizing that everything plays out all over again. Listen to the Lutece's dialogue in the boat, and then look at all of the hints that Booker is simply repeating everything.
This is another thing I'm not sure on. I can't be quite sure whether Booker himself is repeating things, or as if someone mentioned earlier, the Lutece's are merely seeing the events occur in different multiverses with different Comstock/Booker universes colliding. Their jokes to me don't seem to be based on a single Booker repeating things, but from their observations of other universe's Bookers attempting to accomplish the same rescue Liz task.
It's weird though, because while Booker always flips heads, he still has the 'choice' of picking out the bird or cage, killing Slate or not, etc. We don't see how these things change the scope of the story (if they do at all), but that still means that they're technically separate universes each time you make a decision.
Oh, that reminds me. Right before the raffle you get a telegram, did anyone figure out who SENDS that telegram with the warning? That was the only loose end I haven't been able to account for yet.
It's from Lutece. Her/his name is on the card.
