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.<ref>{{Cite web |url=https://retroclone.jottit.com/ |title=Retro-clone RPGs |access-date=2012-09-06 |archive-url=https://web.archive.org/web/20160403090523/https://retroclone.jottit.com/ |archive-date=2016-04-03 |url-status=dead }}</ref>
