RuneQuest is a fantasy role-playing game first published in 1978 by Chaosium, created by Steve Perrin and set in Greg Stafford's mythical world of Glorantha. RuneQuest was notable for its original gaming system (designed around a percentile die and with an early implementation of skill rules). There have been several incarnations of the game. The most recent version was released in July 2012 by The Design Mechanism under the title RuneQuest 6.
