Integrating with an existing game

If you have a game with rules, mechanics, etc., already going, and you want to try it out with the LITD system, here's what I'd recommend:

  • Copy your game to a new project, of course!
  • Delete all of your GM instructions - really!
  • Delete all files and filetypes associated with mechanics and tracking, including:
    • Campaign logs, chapters, memories, archives, etc.
    • Clocks, threads, plotlines, etc.
    • Relationship files
  • Keep:
    • Characters
    • World properties: Lore, Items, Monsters, Locations, etc.
    • Character properties: Classes, Backgrounds, Species, etc.
  • Update:
    • Your existing character sheets to include properties connected to LITD mechanics:
      • Abilities
      • Relationship tags
      • Memories
      • Action Ratings (can use existing skill scores, just convert to a 0-4 scale)
      • Stress
      • Trauma
      • Doomed
      • Harm
      • Force
      • Advancement - New Ability Cost
      • Advancement - Action Rating Cost
    • The Reminders pinned file to note anything critical about your game's themes or style.
