Sorry if I speak out of turn, but a couple questions... is there significance to Booker helping Elizabeth into the pipes to kill Fitzroy? Is it nothing but a nod to the Big Daddy/Little Sister dynamic?
And also, when was Shiny Happy People played?
Also, is some of the alternative timeline and choices being shown to us at the end of the game... with infinite possibilities and locations... is that a nod to game replayability with choice based themes, or is it possibly referring to so many different people playing a game differently than others so that in a stretch, my Elizabeth and DeWitt is different than your Elizabeth and DeWitt? I want to get a message like that of the first game: that there ultimately was no choice to the player of a game, versus this one: infinite choices.
Also, why did it appear that the people in Comstock House were phasing in and out of reality?
