Legend
I can remember being younger than 10 and playing Hillsfar on my grandmother's 386. Well, attempting to play Hillsfar, except for the part where you jump your horse over things I don't think I made much progress. At this age I unironically wondered what a "ling" was and what it meant to be 1/2 of one, no joke. I didn't properly discover D&D for almost a decade afterwards/
Anyway, is Hillsfar that one of the Goldbox games of which you speak? I think I vaguely recall Hillsfar being a place in the FR.
(And I get it, it's a huge world with a TON of history, but I would bet not as much so as Shadowrun (which has, I can safely say having written for it, one of the most ginormous, detailed, and convoluted metaplots of all time) and I can still give people a "short version" of Shadowrun in 1000 words or less, you just have to, y'know, leave a lot of stuff out.)
Hillsfar is in the Moonsea region.
