I think a nice addition to the game would be the option to rebuild the current two locations where the only living NPC's are currently. Even if completion of the quests just changes the aesthetics of the area. They all live in complete destitute and you're capable of building/repairing anything you encounter for your own purposes. Or being able to move them to a new safe home since they're all scared of the events preceding it.

Sad admission; when I built my new home elsewhere, I made a bunch of bots not because I needed them but because the island is lonely. I want NPC's to enjoy the comforts from the fruits of my labor.
