Natural cave galleries.

These have always been kind of anti-climactic, I'd love to see them actually precipitate something, contain something, etc. To in some way be either interesting, useful, or both.

Maybe a rare resource? An ore boulder? A cluster of cave centipedes or a Centipede dungeon?

yeah what this guy said

The more I think about it, the more I'm liking the idea I presented earlier. Specifically, if it's a cluster of resources, like a thick stalagoom cluster, a bunch of centipedes, etc.

Bump because I still hate these and not only do they ruin ore nodes but to actually make use of them you either have to continue playing minesweeper in the direction the gallery has opened since you have no clue of which adjacent walls could be cave-in tiles completely negating the usefulness of the opening that has been created or you build a mine support which negates your previous minesweeper work anyways.

Bad mechanic is bad.
