Super High School Level Swerver

    So on the note of really kinda fantastic 999-y Japanese adventure games, Dangan Ronpa is totally a thing. It's another 2010 mystery game like 999, but it's a lot crazier. 15 high school students ranging from a star teen idol to a super wrestler girl get trapped in their new school by a weird bear... robot... thing. It's got some pretty interesting tunes and instead of 999's smaller, more valuable cast, you know pretty much everything about all the characters to begin with. There's a lot to learn, obviously, but the point of the game is that to escape the school the students must kill each other without being found out, so it's more of a murder mystery and characters are put down at a higher rate. All of the characters are very simple archetypes at a glance, but the game does some really interesting stuff with them and subverts a lot of tropes in some shocking ways. It's just a kinda cool thing. Also, it's exclusive to Japan, so there's that.

Plus all the character designs are by this sculptor guy, so they go beyond the expected anime style.
