> This is fun and neat, and looks fantastic, but the generated maps are basically nonsensical, aren't they?

WFC lets you address that though with extra constraints. e.g. my bot today generated a church inside a river loop[0] - completely useless! But I could add a rule that says "if you place the church-above-river tile, the tile above that cannot be anything horizontally blocking" (obviously after tagging any relevant tiles as "horizontally blocking" in the tileset) and that would prevent "church in a river loop" situations.

(I've already been working on some extra rules because, e.g., I don't like the one-edge-castle-wall tiles being placed next to each other - you get tiny pasty shaped castles and I hate them.)
