Gardasiyal 3: Deeds of Glory
"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 imcomplete Swords & 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.
