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.
  • 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.
