Open gaming is a movement within the tabletop role-playing game (RPG) industry with superficial similarities to the open source software movement. [1] The key aspect is that copyright holders license their works under public copyright licenses that permit others to make copies or create derivative works of the game.
A number of role-playing game publishers have joined the open gaming movement, largely as a result of the release of the original System Reference Document (SRD) by Wizards of the Coast, which consisted of the core rules of Dungeons & Dragons 3rd edition. Open gaming has also been popular among small press role-playing game and supplement authors.
The use of the term open gaming began with the publication of the original SRD and the simultaneous release of the Open Game License (OGL). However, role-playing games had been licensed under open and free content licenses before this. [1]
The Fudge role-playing game system was created in 1992 by Steffan O'Sullivan with extensive help from the rec.games.design community. The name stood for "Freeform Universal Donated Game Engine" until Steffan O'Sullivan changed 'donated' to 'DIY' in 1995.
One reason why Fudge succeeded is that the author released it under the "FUDGE Legal Notice", a license that removed most restrictions on non-commercial use. However the FUDGE Legal Notice (more commonly known as simply "the Fudge license") was never intended to cover any work other than its eponymous role-playing game. Derivative works which were to be distributed for a fee required written permission from Fudge's author, Steffan O'Sullivan. The details of the Fudge Legal Notice were modified and expanded from time to time as O'Sullivan updated his work, but the essential elements of the license remained unchanged. The 1993 FUDGE Legal Notice allowed reprinting of the Fudge rules, including in otherwise commercial works, as long as certain conditions were met. The 1995 FUDGE Legal Notice permitted the creation of derivative works for personal use and for publication in periodicals.
In March 2004, Grey Ghost Games acquired the copyright of Fudge, and on April 6, 2005, they released a version of Fudge under the Open Game License, making it open for commercial use.
The phrase "opensource roleplaying" was used as early as 1999 by the Dominion Rules role-playing system, the license of which permitted supplementary material to be written for its rules. Another "open" system was the Circe role-playing system, published by the WorldForge project under the GNU Free Documentation License (GFDL). Gods & Monsters, created by Jerry Stratton, was also distributed under GFDL in 2013. [2]
Despite Fudge and other games, the open gaming movement did not gain widespread recognition within the role-playing game industry until 2000, when Wizards of the Coast (WotC) published portions of the 3rd Edition of Dungeons & Dragons as the System Reference Document under the Open Game License. This move was driven by Ryan Dancey then Brand Manager for WotC, who drafted the Open Game License and first coined the term "open gaming" with respect to role-playing games.
The Open Gaming Foundation (OGF) was founded by Ryan Dancey as an independent forum for discussion of open gaming among the members of the fledgling open gaming movement. The OGF consisted of a web site and a series of mailing lists, including the OGF-L list (for general discussion of open gaming licensing issues) and the OGF-d20-L list (for discussion of d20-specific issues).
The most common criticism of the OGF was that it was primarily a venue for publicizing Wizards of the Coast. Ryan Dancey was an employee of WotC, and discussion on the mailing lists tended to focus on d20 and the OGL (both owned by WotC) rather than on open gaming in general.
The OGF maintained a definition of an "open game license" while it was active, with two criteria:
The Foundation explicitly stated that the first condition excludes licences that ban commercial use. The second requirement is intended to ensure that the rights granted by the licence are inalienable. [3]
The OGL gained immediate popularity with commercial role-playing game publishers. However, the OGL was criticized (primarily by independent role-playing game developers) for being insufficiently "open", and for being controlled by the market leader Wizards of the Coast. In response to this, and in an attempt to shift support away from the OGL and toward more open licenses, several alternatives to the OGL were suggested and drafted. Similarly, the popularity of the OGL inspired others to create their own, specific open content licenses. Virtually none of these gained acceptance beyond the works of the licenses' own authors, and many have since been abandoned.
Linda Codega, for Io9 in January 2023, reported on the details from a leaked full copy of an update to the OGL including updated terms such as no longer authorizing use of the OGL1.0. [4] Codega highlighted that "if the original license is in fact no longer viable, every single licensed publisher will be affected by the new agreement. [...] The main takeaway from the leaked OGL 1.1 draft document is that WotC is keeping power close at hand". [4] Following this, Paizo announced a new Open RPG Creative License (ORC) as a direct response to the reported changes to the OGL. Additional publishers, such as Kobold Press, Chaosium, Green Ronin, Legendary Games, and Rogue Genius Games, will be part of the ORC development process. [5] [6] The ORC will be an open, perpetual, and irrevocable system-agnostic license [5] [6] with legal development paid for by Paizo "under the legal guidance of Azora Law", however, the license "will not be owned by Paizo, nor will it be owned by any company who makes money publishing RPGs". [7] Paizo plans to find a "nonprofit with a history of open source values to own this license" and stated that "Azora Law's ownership of the process and stewardship should provide a safe harbor against any company being bought, sold, or changing management in the future and attempting to rescind rights or nullify sections of the license". [7] [8]
Free League Publishing announced two licenses, for its Year Zero game system and another for its upcoming fantasy RPG Dragonbane. [11]
The most common open gaming license in use by commercial role-playing game publishers is the OGL. There are many publishers currently producing material based on the first System Reference Document, and many which make their products available under the OGL but which use game systems not based on the SRD.
Wizards of the Coast used the non-open Game System License for the 4th edition of Dungeons & Dragons, but released a new System Reference Document in 2015 for the 5th edition licensed under the OGL. [12] [13]
The Open Gaming Foundation describes these licences as ‘Known Open Gaming Licenses’. [14]
The following games are fully or partly under an Open Gaming Foundation-approved license or a free culture license.
A number of fans and publishers have used existing open game content to create rules systems which closely emulate older editions of games that are no longer supported, and released those rules systems under an open license. The term "retro-clone" was coined by Goblinoid Games, the publisher of Labyrinth Lord. [27]
Notable examples of retro-clone games are Basic Fantasy RPG (based on Basic Dungeons & Dragons), OSRIC (based on 1st edition Advanced Dungeons & Dragons ), Labyrinth Lord (based on Basic Dungeons & Dragons), and Swords & Wizardry (based on original Dungeons & Dragons).
Dungeons & Dragons is a fantasy tabletop role-playing game (TTRPG) originally created and designed by Gary Gygax and Dave Arneson. The game was first published in 1974 by Tactical Studies Rules, Inc. (TSR). It has been published by Wizards of the Coast, later a subsidiary of Hasbro, since 1997. The game was derived from miniature wargames, with a variation of the 1971 game Chainmail serving as the initial rule system. D&D's publication is commonly recognized as the beginning of modern role-playing games and the role-playing game industry, which also deeply influenced video games, especially the role-playing video game genre.
Wizards of the Coast LLC is an American publisher of games, most of which are based on fantasy and science-fiction themes, and formerly an operator of retail game stores.

The d20 System is a role-playing game system published in 2000 by Wizards of the Coast, originally developed for the 3rd edition of Dungeons & Dragons. The system is named after the 20-sided dice which are central to the core mechanics of many actions in the game.
The Open Game License (OGL) is a public copyright license by Wizards of the Coast that may be used by tabletop role-playing game developers to grant permission to modify, copy, and redistribute some of the content designed for their games, notably game mechanics. However, they must share-alike copies and derivative works.
In the open gaming movement, a System Reference Document (SRD) is a reference for a role-playing game's mechanics licensed under a public copyright license to allow other publishers to make material compatible with that game. In 2000, Wizards of the Coast pioneered this by releasing a SRD for Dungeons & Dragons 3rd edition under their Open Game License (OGL).
Several different editions of the Dungeons & Dragons (D&D) fantasy role-playing game have been produced since 1974. The current publisher of D&D, Wizards of the Coast, produces new materials only for the most current edition of the game. However, many D&D fans continue to play older versions of the game and some third-party companies continue to publish materials compatible with these older editions.
PCGen is a character creation and role-playing game playing aid program for d20 System-based games, such as Dungeons & Dragons.
The history of role-playing games began when disparate traditions of historical reenactment, improvisational theatre, and parlour games combined with the rulesets of fantasy wargames in the 1970s to give rise to tabletop role-playing games (TTRPGs). Multiple TTRPGs were produced between the 1970s and early 1990s. In the 1990s, TTRPGs faced a decline in popularity. Indie role-playing game design communities arose on the internet in the early 2000s and introduced new ideas. In the late 2010s and early 2020s, TTRPGs experienced renewed popularity due to videoconferencing, the rise of actual play, and online marketplaces.
