Edit: "Is there a concept *of "unshareable items"? Does Starbound have this concept? If I wanted to make an item that a player can craft for themselves, but they can't give it away. If not, maybe there are some tricks to accomplish this, like if it's possible to make an item undroppable, or be automatically destroyed when dropped or picked up?
Maybe? Are items stored in a fundamentally different way as items in your inventory and in the game world? Take advantage of that, make it simply not produce anything when you try to drop it.
