Things I have considered:
- 2e nwod Werewolf game with a heavy focus on plot and territory (currently working on this).
- Monsterhearts game
- Apocalypse/Fallout/Mad Max like game with a heavy focus on survival simulation and social RP.
- Science-Fantasy game. Magic and Steamtech. Something that combines elements from both that I love.
- I actually think a MU set in one of the Magic the Gathering settings could be great. Dominaria or Ravnica.
I also love my games to be gritty/high lethality. Which is missing on almost every Mush I have tried.
