Copped it on steam summer sale and holy shit what a fantastic game

Spoilers

For those that stuck around after the credits you see Booker and you hear a baby's voice in the next room presumed to be Anna. We know that Booker and Comstock are the same people just from other realities but we are lead to believe that by drowning him before he can either accept or reject the baptism it stops everything.

Think maybe this still goes on no matter what or somehow after they both died another version of the girl went back and stopped even more from happening? We've seen other tears happen like the one from 1985 I believe with "everybody rules the world" playing through the portal.

Love that the game makes me think that much after the fact
