In case someone has been waiting for any of these to appear: None of these will be published, even though they're great fun to play: Saqaliba will get me killed on the internet if I try to publish it in English; YOPA turned out to not really need the Lovecraftian horror; and Oguleh requires time from others than myself.
However, Roots of Soledad - which looks like it might be published for real by a real publisher - uses the same method/system; it's a direct descendant of YOPA. Magical realism instead of Lovecraft.
