Map Programs!?!?!?! (Patreon)

I'm screwing around with some different map programs right now, both for my own notes and a possible future release! (Gotta get those Goals! <3) There are a great many programs out there, but most are geared towards D&D. It's useful for getting some general overviews down, like the one above, but not so hot for detail. Eventually I'd like to have a large scale map where one could zoom in to see the passages and trails, maybe even get a sense for the way the room is arranged.

In my brain it's like I want to be looking down at a game board (think Clue). I want to know exactly which rooms connect to which others so I can start organizing who will be where, which choices you can make, and which path that will lead you down. At the same time, I also need a vertical vivisection because there are basements, grottos, underground cavers, lake towns, et cetera!

DETAILS!!

If anyone would like to suggest some really good mapping programs, I'm open.

NOTE: The map above should not be counted as canonical. I'm just messing around with some basic placement and seeing which program I'd like to use.
