@MisterBoring Not sure how close it was to what you’re saying, but ye olde Horror Mu* had players come up with a general concept (like strong character, academic character) and they played non-related arcs, but the same concept? I never played and could be off base, but that was my understanding.

Champions games have used the staff builders to help players get what they wanted out of the mechanics, which is sort of close I believe.

As an aside, I like the idea of collaboration between player/staff to get what both want mutually.
