@SJohnRoss Hi John. Have you taken a look at the Swedish "Forbidden Lands" RPG? I feel that their Raven's Purge ticks a lot of your definition of
#HTTRPG :
No "adventures", only "locations", with people living or coming, with their own goals.
Problems have no closed-choice solutions.
Many factions have the potential to become allies or ennemies.
There's a McGuffin quest (a 6-jeweled crown with 3 missing jewels) but it's entirely optional: you can do anything you want with these items, like give or trade them for things you want, or just ignore them and pursue other interests.
A dozen major NPC are described, with their links and intentions, and usual dwellings.
Productive exploration with surprising locations, and random encounters but still meaningful, since half of them are linked to some factions.
