Shameless plug: I wrote a pretty lengthy analysis of the musical gestures in the original Nier soundtrack and, as predicted, a whole bunch of them came back in the Automata soundtrack. I’m still getting around to a more thorough analysis of the Automata soundtrack, but for now give this a shot!

I would like to nominate a bit of an oddity: Nier. The setting is technically post-apocalypse, but during the time that you play (and especially once you do playthrough B) I would consider it a dystopia.
Nier thrives so thoroughly on closet horror that I would almost call it a closet dystopia.
