Quote from: estar;1033594My How to Make a Sandbox has procedures and tips for fleshing out an arbitrary area.

I think your system is aimed at a bit larger scale Rob. For doing my own mini-sandbox I'm really thinking of something that ideally looks more like an above ground dungeon in terms of detail & scale, eg Horror on the Hill:



Or something like what you could build with the wilderness tiles from 'Descent', where the wilderness is mapped as if it were a dungeon. Hmm.

If it helps my experience is that the process is inherently fractal in nature. That you do the same things regardless of scale until you start hitting the level of individual buildings. What differs is that you ignore steps 1 to 3 and change step 4 to be X by Y. In fact despite my explicit call out for a 200 mile by 150 mile area, the example, the Island of Piall, is only 15 miles by 15 miles.

That!  I can agree with.  So something like the ones in 5e's Out of The Abyss's Chapter 2.  Gotcha.  Hmm, Sadly, I don't know any game setting, but I'd be curious in finding more.
