So the first to respond to my request for a #pbm game setup was Reality Simulations Inc. with setup instructions for Hyborian War.
I had assumed I'd get the full manual, but I guess when you request a setup on the website they just send you the setup rules.
Still better than either Monster Island and DungeonWorld (not the #ttrpg of the same name), which both are done by British companies. I don't even know if it's their fault or the mess at Royal Mail right now.
