There are a lot of temples and ruins dotting the Starbound universe. Some of them are harder to dig through than others; particularly as the planet goes up in level. As much as I enjoy digging through these temples, it does get redundant after a while. Maybe there could be a non-stackable major artifact hidden at the bottom of it? It could even be named randomly, much like the enemy NPCs are. On acquiring this artifact, it could be sold to a curator and collector of antiquities, possibly stationed at the portal moon base, for a sizable sum, proportional to the level of the planet it was found on. This would give everyone an active reason to clean out the temples, burial sites, castles, sewers, and hunting camps.
