Game System License
Wizards of the Coast released the Game System License to the public on the 17th of June 2008. This document allowed third-party publishers to create products compatible with Dungeons & Dragons 4th Edition. The license granted use of a specific System Reference Document listing trademarks and short phrases. It did not contain actual game rules itself. Publishers received a logo to place on their products stating compatibility. Wizards of the Coast retained the right to update the license at any time. Any updates automatically affected all existing licensees. In case of litigation, licensees were required to pay the legal costs of Wizards of the Coast. This structure differed significantly from the previous Open Game License used for earlier editions.
Necromancer Games co-founder Clark Peterson called the agreement an unmitigated disaster in August 2008. His company decided to cease efforts supporting the new edition immediately after reviewing terms. Chris Pramas of Green Ronin stated they did not feel treated as valued partners by the licensor. Fred Hicks of One Bad Egg described his initial reaction as crushing disappointment. He viewed specific poison pill clauses as particularly troubling despite creating a separate legal entity to protect Evil Hat Productions. Mongoose and Goodman Games produced third party products while others refused to participate. ICv2 highlighted that reactions remained mixed at best throughout the summer of 2008. The industry had come to expect certain freedoms with D&D rules before this release.
The license contained restrictions preventing compatibility with older editions of the game system. Anyone using it could not publish under the old Open Game License simultaneously. This effectively forced publishers to stop producing anything compatible with Third Edition if they wanted Fourth Edition supplements. Wizards of the Coast removed much of the more restrictive language later, but damage was already done. The restriction represented a direct attack on the OGL which WOTC was legally unable to revoke. Many publishers suggested this limitation fostered negative feelings within RPG communities against the leader. Academics Benoît Demil and Xavier Lecocq noted these incompatibilities drove away third-party producers for the short-lived 4th Edition. Two companies signed on for 4th Edition though to little benefit for themselves.
Mordicai Knode wrote in 2012 that Pathfinder played a central part in the edition wars between competing systems. Paizo did not take sides officially yet provided a convenient flag for those finding Fourth Edition lacking. They rallied around the third party publishing agreement issues surrounding the new version. The poison pill clause prevented anyone from publishing under the old license while using the new one. This dynamic helped create a situation where Paizo created Pathfinder to compete directly with Wizards' new version. Bob Byrne commented that Necromancer effectively packed it in while Paizo created an alternative system. The third party publishing agreement for the Fourth Edition did not help matters during this period of intense competition. The community found itself divided over which ruleset to support moving forward.
Academic analysis in Revue d'économie industrial published in 2014 showed how the license drove away third-party producers. Many publishers who previously supported the d20 system decided to develop their own set of rules instead. These groups began publishing their own material under the OGL rather than accepting restrictive terms. A lot of publishers rejected the 4th Edition of D&D entirely due to these restrictions. The restriction fostered negative feelings within RPG communities against the leader company. Bob Byrne noted that two companies signed on though to little benefit for themselves. Goodman Games and Mongoose Publishing were among the few remaining participants. The economic impact extended beyond simple sales figures into long-term industry relationships. Publishers felt forced to choose between compatibility and creative freedom.
