I wonder what the quickest map maker would be - I know you tend to use public records and architecture diagrams and draw over them, and I think that's my favorite for realism, but I wonder if there's an architecture program, or videogame tilemap painter, or other program that we could point to for quickly populating maps. All the architectureal programs I've used before have either killed their free trials, or are pretty unintuitive.
I do like that you're posting them here, it's great that we're getting a start on a communal resource pool for GMs. Do we have an archive some of the existing assets in a public Google or Mega drive? It'd be interesting to see what new DMs remix out of existing materials
