Over the last twenty four hours we've been looking at original Dungeons & Dragons rpg & the original Traveller rpg on the OD&D forums here. And up pops up Chaosium's Thieves' World another artifact from an earlier time peroid in gaming.
And let's look at the wiki for the Thieves' World box set; "The Thieves' World Complete Sanctuary Adventure Pack is a boxed set published by Chaosium in 1981, containing: 1) The Player's Guide to Sanctuary; 2) The Gamemaster's Guide to Sanctuary; 3) Personalities of Sanctuary; 4) Map of Sanctuary; 5) Map of the Maze; 6) Map of the Maze Underground.
Just as the Thieves' World series of books was a shared universe with multiple authors using a common setting, Chaosium initially positioned the Thieves' World RPG as a setting that could be used with multiple game systems. The Personalities of Sanctuary included statistics and gaming notes for Advanced Dungeons & Dragons, Adventures in Fantasy, Chivalry & Sorcery, DragonQuest, Dungeons & Dragons, The Fantasy Trip, RuneQuest, Traveller, and Tunnels & Trolls. Later products in the series provided stats only for RuneQuest and Rolemaster/Middle-earth Role Playing. Thieves' World series contributing novelists Lynn Abbey, Poul Anderson, Robert Asprin, Marion Zimmer Bradley, John Brunner, Christine DeWees, David Drake, Philip José Farmer, Joe Haldeman, Janet Morris, Andrew Offutt, and A.E. van Vogt wrote descriptions, essays, and short stories for the player and game master volumes in the box set, and game designers Dave Arneson, Eric Goldberg, Rudy Kraft, Wes Ives, Stephen Marsh, Midkemia Press, Marc W. Miller, Steve Perrin, Lawrence Schick, and Ken St. Andre helped translate the world into the various game systems"
What this little artifact from another era does right is actually merge Cepheus Engine style rpg rules with how to handle royals & planetary governors in 2d6 Science Fiction rpg's. And while Challenge magazine had a few articles on this very subject. These days the Barbaric! rpg would be perfect to merge your Cepheus Engine space elements with a Sword & Sorcery asthetic..
Sanctuary may be the only places where the elders & the wizards still remember their inhuman trading partners. Perhaps the back corporate servers of the Clement Sector & Earth sector mega corporations might remember as well. But with such a glut of info would they know?!
