Terraria NPC Happiness Guide

Terraria's new NPC system is quite similar to Fallout Shelter's, where you'll have to surrender to whatever guests need to maintain happiness. With such an odd and diverse cast of characters to watch out for, they can get quite picky and possibly angry with things like close neighbors and their chosen biomes. To keep your community running smoothly, here's how to maximize everyone's happiness.

Characters and preferences

It should be noted that if you meet each of their preferences, they receive a 5% to 10% bonus - depending on whether they like or like the established executive or the neighbor.
