Only two publications were published, the
Ringworld role-playing game box set itself, and the
Ringworld Companion, both in 1984 by Chaosium. The magazine
Different Worlds, issue 37, featured a
Ringworld adventure, "Louis Wu & His Motley Crew." The article "The Dolphins of Known Space: A new race for the Ringworld Game" appeared in
Dragon Magazine issue 95.
Ringworld Box Set The
Ringworld role-playing game box set was titled "Larry Niven's Ringworld: Roleplaying Adventure Beneath the Great Arch", referring to the way the Ringworld looked from its interior surface. The authors are credited as
Greg Stafford, John Hewitt,
Sherman Kahn,
Lynn Willis,
Sandy Petersen,
Rudy Kraft,
Charlie Krank,
Ed Gore, and
Jeff Okamoto. It came in a box set with four books: the Explorer Book, Technology Book, Gamemasters Book, and Creatures Book, a sheet of cardboard miniatures, reference and character sheets, and a set of
dice: 2d20 (actually dice with two sets of digits 0 to 9), 1d8, and 2d6.
Explorer Book This book begins with a character sheet. It introduces role-playing games, then covers character creation, skill use, and combat. It presents a detailed history of humanity between the 20th and 29th centuries. It then describes eleven human worlds: Belt (the
asteroid belt), Canyon, Down, Gummidgy, Home, Jinx, Margrave, Plateau, Silvereyes, "We Made It" and Wunderland. Finally, it gives rules for non-human, Kzin or Puppeteer, player characters, and a glossary.
Gamemaster Book The Gamemaster Book begins with technical essays on the Ringworld, from physical construction, to life on the ring, with diagrams. There is a section on the "City Builders"—a Ringworld race that dominated the Ringworld, built floating cities, and sent spaceships to explore other worlds, until a mysterious technological virus destroyed their empire. Another section lists unanswered questions about the Ringworld. There are suggestions for creating scenarios and campaigns, and information on technology of various humanoid species of the Ringworld, and additional rules, including gravity, Credit Rating, and
psionics. There is also an introductory scenario ("The Journey of the Catseye") intended to begin a Ringworld campaign. The characters are hired by Captain Gregor Lopez, famous explorer, for a journey to the Ringworld that does not go completely as planned.
Technology Book The Technology Book gives rules and descriptions of the equipment employed by the explorers of the 29th century, categorized into generators, computers, medical equipment, tools, vehicles, weapons and defenses.
Creature Book The Creature Book gives rules and descriptions for creatures, divided into Aliens, Humanoids, Animals and Plants. Many races get specialized hit location tables, characteristic maxima and minima, skills and traits.
Ringworld Companion The
Ringworld Companion supplement was published not long after the box set. The authors are credited as Greg Stafford, John Hewitt, Sherman Kahn, Lynn Willis, Sandy Petersen, Rudy Kraft, and Charlie Krank. The book starts with a diagram of the Ringworld and its star, EC-1752, new humanoids, aliens, plants and animals, technological objects, and original errata. There is some information on
spaceships (Human and City Builder),
hyperspace, a map of Human Space, and statistics for vehicles used on the Ringworld. Then there is a new race, the "Agamans", desert nomads, and a scenario involving them, "The Sand Eaters". Finally, there is a three part scenario named "The Kaladians", about the defense of travelling merchants. Both scenarios can be integrated into the campaign given in the basic set. None of these three additional races appear in any of the
Ringworld novels. ==Reception==
