subtitle: Science Fantasy Adventures in the Star-Faring Ancient Past of Professor M.A.R. Barker's World of Tekumel website blurb: These rules include character generation, PSY and Super-Scientific powers, and sufficient combat and adventuring rules to get a party through a space dungeon. The system is essentially an iteration of my Synthetic 75 Science Fantasy Retro Roleplaying concept, a mash up of (what I consider) the best from the hottest RPGs of 1975, Dungeons & Dragons and Prof. M.A.R. Barker's Tekumel: Empire of the Petal Throne. The draft playtest rules will be expanded with additional material and will constitute Book 1: Science Fantasy Adventures. Book 2: Space Monsters will include a selection of inimical alien fiends, bug-eyed monsters, inter-dimensional horrors, and other terrible creatures and a system for randomly generating new space monsters.
