I’m writing a game, not an Apocalypse World hack in strictest terms, but I did write an Agenda for the GM:
• Keep the people real with real problems, real goals, and real lives that continue in the absence of the players.
• Keep the world strange, mysterious, and deadly.
• Fill the players’ character’s lives with danger and opportunity.
• Play to explore the definition of science fantasy, in any and every way possible.
Got a working title yet?
Fantasy Heartbreaker
That agenda makes it sound like Quantum Leap or Doctor Who.
