Described by One Proud Bavarian as the “Pinnacle of Roleplaying” for mods of Crusader Kings 3, check out these many reviews of the mod:
Hello World of Darkness!
Princes of Darkness mod is an adaptation of the World of Darkness Role-Playing Games , particularly Vampire: the Masquerade, for the grand strategy game Crusader Kings. Its the RPG you play on a map rather than an RPG you play as a FPS or Isometric squads. In this mod, you play as the supernatural ruler of a province.
