A video for my old Traveller group, most of which ended their (human) life on a mission codenamed “suprematism”:
Back then, I had to make a to-scale “model” of the ringworld using a pearl for the sun and some serious knitting for the ring. Would only fit on the floor, and furniture had to be moved. The Ringworld was data modelled via a MySQL database that had an Universal Ring World Civilization Profile (URWCP) for every Earth Size equivalence, balkanization could occur, obviously. Space Travel Tech Level was capped at 9 or 10, because of in-game historic reasons. I remember one of the most awesome fight scenes in my gaming career when there was a rocket-shuttle-ringworlder-marines assault on the HMS Malewitsch’s crew, that was fought off with yucky and creative use of a Cziltang-Brone. That was near one of the stabilizer jets on the ledge seen in the vid.
