RuneQuest

RuneQuest (commonly abbreviated as RQ) is a fantasy tabletop role-playing game originally designed by Steve Perrin, Ray Turney, Steve Henderson, and Warren James, and set in Greg Stafford's mythical world of Glorantha. It was first published in 1978 by The Chaosium. Beginning in 1984, publication passed between a number of companies, including Avalon Hill, Mongoose Publishing, and The Design Mechanism, before finally returning to Chaosium in 2016. RuneQuest is notable for its system, designed around percentile dice and an early implementation of skill rules, which became the basis for numerous other games. There have been several editions of the game.
