I, too, have a copy of High Fantasy, along with Adventures in High Fantasy, got them both for $5 at a model train store in Austin circa 2000. Same store also had all the GURPS Conan books, but I passed them up for some stupid reason.
No idea how obscure these are, but I was digging around and found Ninja Burger, Ork, Aria, and Reich Star. Gonna go through all those boxes soon...
