Gardasiyal
A non-traditional fantasy game set on a unique alien world called ""Tekumel""¸ with strong Hindu and Aztec flavor rather than European. The setting was previously published in two games¸Empire of the Petal Throne(1975) and the imcompleteSwords & Glory(1983). In this game¸ the rules were wholly rewritten by Neil Cauley. It uses a percentile system where the base chance of success is 70% and the die roll is modified by (+difficulty) and (-skill). There is also another game set in the same world published by Guardians of Order in 2005¸Tekumel. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H. Kim
