From publishers blurb of Greenjackers:
Based on the Passkey System (first used in Stravagante!) Greenjackers! features player-centered collaborative role-play, and quick character creation with lots of room for customisation. The game can be played with a GM (Mod) or without, providing a Mod Guide containing a variety of prompt tables for generating missions, NPCs, locations and more.
