Victor Raymond sent along word to me that the Tékumel Foundation, the non-profit corporation charged with supporting and protecting the works of Professor M.A.R. Barker, is preparing to release "the original, never-before-released rules draft for Empire of the Petal Throne. As such there are some subtle and some not-so-subtle differences between it and the published version from TSR." Though the price for the PDF version of the unreleased EPT is still being determined, Victor says that it'll likely be under $20. A print-on-demand version of the same is under discussion as well, though when it will be available is still uncertain. The PDF will be made available through RPGNow/DriveThruRPG, where a wide variety of other Tékumel-related gaming products are already available.
As a teaser, here's a photograph of a copy of the original EPT rules, put together by Professor Barker in 1974, as well as one of the earliest maps of Tékumel, drawn by the professor. The Foundation intends to release the map to the public too at some point, but is still deciding the best way to do so. Once again, I stand in awe of not just what Professor Barker has done but what the Foundation is doing to promote and support his work. It's a pity more of the hobby's creators aren't in a similar position to be able to preserve and make available their works.
