Collecting Judges Guild Products

In the 1970s and 1980s, Judges Guild was one of the leading publishers of supplementary material for Dungeons & Dragons. During this period, they also released modules for such roleplaying classics as Traveller, Advanced Dungeons & Dragons, DragonQuest, RuneQuest, Villains & Vigilantes, Superhero 2044, and Empire of the Petal Throne. Those interested in collecting Judges Guild products should also be aware of City State of the Invincible Overlord, as it was the first city supplement ever published for a roleplaying system.

City State of the Invincible Overlord

Judges Guild was founded in 1976 by Bill Owen and Bob Bledsaw, and the enterprise was incorporated in 1978. During their peak years, the company had over 250 items in print, but they were out of business by 1985. Mayfair Games republished City-State of the Invincible Overlord in 1987, and Judges Guild would return with yet another revised version in 1999.

A D20 version of this classic city supplement would be released in 2002 by Necromancer Games, and Adventure Games Publishing purchased the rights to publish Wilderlands of High Fantasy in 2006. In 2007, collectible Judges Guild products once again made the news when it was announced that Eostros Games and Goodman Games would be publishing revised versions of three classic modules for the D20 system.

Dungeons & Dragons Collectibles from Judges Guild

D&D has always been the most successful roleplaying game, and Judges Guild was once a leader in providing third-party modules and supplements. While many other items were released over the years, those with a passion for collecting Judges Guild products may want to target the following as especially valuable:

  • An edition of Inferno that includes the original manuscript and printing plates was available at Noble Knight when I wrote this for $1,995.
  • I found a supplement titled Character Chronicle Cards for  $249.95.
  • I also found an adventure titled House on Hangman’s Hill for – $39.90 on eBay.

Dungeoneer Magazine

Judges Guild released several publication over the years, and Dungeoneer Magazine specialized in monsters, adventures, and maps for Dungeons & Dragons. Depending on the issue and its condition, you’ll find these available for between $75 and $125 on eBay and other sites that focus on selling out of print RPG supplements.

  • Dungeoneer #1 “F’chelrak’s Tomb, Fatigue Factors, New Monsters”
  • Dungeoneer #2 “Female Characters, Alcohol in D&D, The Fabled Garden of Merlin”
  • Dungeoneer #3 “Borshak’s Lair, New Monsters”
  • Dungeoneer #4 “The Room of Crooked Magic, The Pharaoh’s Tomb, Metamorphosis Alpha”
  • Dungeoneer #5 “Night of the Walking Wet Part #1, Elementals“
  • Dungeoneer #6 “Idiosyncracies in D&D, Night of the Walking Wet Part #2”
  • Dungeoneer #7 “Metamorphosis Alpha Mini-Dungeon, Barbarians”

Pegasus Magazine

Judges Guild released another magazine, Pegasus, dedicated to serving the needs of roleplayers. Back issues of Pegasus are more affordable than copies of Dungeoneer. Most issues of Pegasus can be bought in excellent condition for $20 or $30 per copy or less.


RuneQuest was created by Chaosium in 1978 and established the dangerous fantasy world of Glorantha. Some of the supplements Judges Guild produced for Runequest include Hellpits of Nightfang, Runequest Judges Shield, Broken Tree Inn, Duck Tower, City of Lei Tabor.


Traveller was the first spacefaring science fiction roleplaying game (unless you count Ken St. Andre’s Spacefaring RPG.) Game Designers’ Workshop product blazed trails in the realm of science fiction roleplaying. Judges Guild published multiple products for use with Traveller.

Some of these Traveller products include Starships & Spacecraft, Science Fiction Campaign Pack, Glimmerdrift Reacher, Doom of the Singing Star, and Fifty Starbases.

Tunnels & Trolls Modules from Judges Guild

Besides creating supplements for Dungeons & Dragon, Judges Guild also released products for the early D&D rival, Tunnels and Trolls. Some of these modules include The Toughest Dungeon in the World, Jungle of Lost Souls, and Rat on a Stick.

I found a Tripod site which claims to list all of Judges Guilds products from the 1970’s and the 1980’s. This might be worth looking at. You can find the site here: Judges Guild products from the 1970s and 1980s. Another list is available at the Acaem site.
