We could do with a referee's toolkit to creating adventures and campaigns, particularly adventures which do not revolve around military action / violence / dungeon crawling / killing everything that so much as twitches / trade.
Adventures for Scholars, Entertainers, and Rogues would sound like fun; travelling about the universe applying Science to understand weird stuff; musicians arranging gigs, acting troupes staging plays, everybody networking with contacts, building a reputation, curating and sanitising your scandals; and living the life of a Stainless Steel Rat, robbing the greedy and the rich blind, hustling, playing the angles, and always making sure you have your exit planned first.
