I still think it's a mess. If Lutece has such a vast understanding of the quantum tears bananza, why does she care if Comstock dies or not, when there are a million billion other universes in which he still lives, and maybe in some of them he's not even being an asshole. Or does she only give shits about her universe? Fair enough, I guess.
Now why does Booker give shits about the other universes? When he finds out that him and Comstock are the same, can't he just go with Lizzie in their own universe and hit Paris, leaving the whole floating city, with generators vital for the functioning of an airship in plain fucking sight, rot and go to hell (Yes, I am bitter because of the final battle.)? It's not like a jaded "war hero" couldn't stand to leaving thousands of lives behind, that he is pretty much hopeless to change. Or he could just travel back to when he was about to commit all those horrendous war crimes and warn himself of who he'll become.
Also, why do I have to go out of my way to understand the plot? I get that plain shooting galleries may not be suitable for exposing a plot as complicated as this one, but a better idea would be to change the gameplay so it would fit the story. Or change the story to fit the gameplay, it's easier that way. Maybe this paragraph doesn't have its place here, this is after all an article about the story of the game, not its gameplay, but Infinite is a game first and a story about what ifs and unexplored racist and religious issues (correct me if I'm wrong, I barely listened to the audio logs) second, and this should be taken into account when considering what information to give to the player regardless, and what to let them find out on their own.
I get the feeling that the game resents me for not being hellbent on collecting audio logs and stuff, but I think this should be an optional thing (unless it's a mystery story, of course), that helps the player immerse into the game's world, making them feel that there is more to it that what they see; you still understand the ending of Skyrim if you didn't read all the books, for example.
