Questworlds is a new RPG by Chaosim Games. It takes the high-level, keyword-based rules of something like Fate or Powered By The Apocalypse and gives them the structure of something a bit less woolly and with a strong sense of progression. It’s perfect for running high pulp, threatre of the mind style games, which makes Bullets and Brimstone sit within its playspace pretty nicely.
