There’s a game in development called Girl Underground, which focuses on a central Girl (in the vein of Alice in Wonderland, Labyrinth, Mirrormask, Spirited Away, etc) having an adventure in a weird secret world, with her companions.
Only The Girl has stats. No one plays the girl. Everyone plays wondrous companions. You roll with The Girl’s stats.
There’s a write up of a playtest AP over here.
I can’t help but think there’s marvelous Doctor Who reskin potential for this.
