Vault 81 is also one of my favorite places in the game (I feel like I say that about pretty much all locations though
) I like that it was an experimental vault, that, despite its original mandate, actually managed to come out of things as a somewhat normal community and an overall pleasant place to live, a rare bright spot on the otherwise dimness of the Wasteland.
Also surprised you didn't show both "before" and "after" with Curie, seeing as Bradberton seems to be heading on that trajectory of machine to man.
