My take on the story

Obviously having something to do with the Institute and androids

Seeing the BOS, I think that they want to push into the Institute for the technology while the androids fight back and you'll have to choose a side
I think the BOS will play a more villainous role in this game and you be more inclined to side with the androids

But where do you fit into it?

My theory is that you are an android and were a part of vault experiment that wanted to see what would happen with a vault filled with androids who think they're humans

This explains how you were able to come out after 2OO years and how you were able to survive outside during the blast
Plus it has some interesting morality issues with the more ethical choices of the Wasteland since you are an android making human decisions
And you have a baby so that would be interesting to see with the android emotions and shit

Most of all, it would make sense in the BOS vs Institute storyline that I'm going for since you would be more important in the conflict

As for how you got into the vault, I think that the nuclear detonation short circuited your systems and that you were one of the few that made it into the vault while the others got destroyed

Something happens that sparks up your systems and you go on to find out how you were able to survive that whole time which leads you into the BOS vs Institute conflict



Anyways that's just my hype coming out lol
What chew think?

Playing as an android? That would explain how the characters treat altering their whole face as if it were a routine thing.

And slowing down time in VATS and the superhuman abilities that the player has
