Decoration! I had to do a lot of devmode setup to get the anima tree island and sunroof working before the game actually started, so I added crystals and 12 legendary obelisks in a ring around the island for flavor. A raider picked up one of the giant crystals and ran away with it(as one does).
It took a few hours of setup before I was able to turn off devmode and actually unpause the game, but I think it was worth it.
