RuneQuest
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.
In Britain in the 1980s, RuneQuest was recognised by the gaming world as one of the 'Big Three' games with the largest market share, the others being Dungeons & Dragons and Traveller.
Setting
With the exception of the Third and Sixth (current) Editions, the default setting for RuneQuest has been the world of Glorantha. However, supplements published by Mongoose showcase other settings. (Young Kingdoms, Sláine and a pirates setting). The first edition of Clockwork & Chivalry, a clockpunk version of the English Civil War, by Cakebread & Walton also used the Mongoose rules before switching to their in-house Renaissance Deluxe system.
