Empire of the Petal Throne

Empire of the Petal Throne is a fantasy role-playing game designed by M. A. R. Barker, based on his Tékumel fictional universe. It was self-published in 1974, then published by TSR, Inc. in 1975. It was one of the first tabletop role-playing games, along with Dungeons & Dragons, and was the first published RPG game setting. Over the subsequent thirty years, several new games were published based on the Tékumel setting; however, to date, none have met with commercial success. While published as fantasy, the game is sometimes classified as science fantasy or, debatably, as science fiction.
