More suggestions:
• Rather than “A Poor Axe” could the name be something like, “Simple Axe” or “Stone Axe”? That way you won’t have “remarkable poor” items. “A” should be removed from item titles in general anyway, to avoid awkward statements on your log.
• When I throw dirt onto shallow water, and dig it up, there is only dirt underneath. Is there a way to have the tile remember that there was water underneath it? Or to have a tile increase its “turn to water” probability when you dig it depending on how close you are to the ocean, or something?
• I’m not sure this is implemented, but if a remarkable pole is used to build, let’s say, a hammer, it should increase the probability that the hammer will be remarkable.
