The idea I have is basically a downriver swamp that was enough of a crossroads to build walkways over it. Over time, it’s been clogged with the detritus of centuries of war from upstream: materiel, corpses, undying warriors left as waste. The near-constant flow had attracted scavengers, making it hard to maintain; and eventually there was nobody left to maintain the walkways.
Figured I'd get a little into the sausage on one particular thing I found that I'll be using quite a bit.
Cyclic dungeon generation is a really, really cool thing that I saw posted about on twitter (from @riseupcomus I believe?), and from there I've seen other people posting about it too. In general it's a great read just for picking out good design patterns for making little moments in a level, dungeon, etc - Zelda is described as the big influence but you can see this kind of technique for design going pretty clearly into a lot of soulslike areas, for instance. So I decided to give the randomization from it a shot! I'm intending a mix of bigger "destination" regions and smaller "interstitial" regions so I'm not terribly worried about the size at this juncture, but it's built such that you can pretty easily compound on it if you want.
