Spiritual Successor / Tabletop Games

  • Pathfinder is Paizo's refinement of Dungeons & Dragons 3.5 edition rules, made after Wizards of the Coast released 4.0 edition and upset a lot of fans because it was completely incompatible with 3.5 and was a sharp change in play-style.
    • Dreamscarred Press has made a habit of taking Dungeons & Dragons's alternate magic systems and porting them to Pathfinder.
      • Psionics were revamped in their Ultimate Psionics book
      • The controversial Tome of Battle was revamped in Path of War
      • Magic of Incarnum's chakra was reworked in Akashic Mysteries
  • The OGL fostered many of these for Advanced Dungeons and Dragons First Edition: Among them are Castles and Crusades, OSRIC, and Labyrinth Lord.
  • Cheapass' Games Kill Doctor Lucky is a spiritual prequel to Clue.
