Npc that wander the world

Many people get a liminal and empty feeling when playing singleplayer especially if they don't have music on. To combat this i present NPC's that wander the world. NPC's will act like normal players chop down trees, build houses, mine, etc. Like most NPC's they'll send you on useless quest for a reward. Along with NPC's is a friendship meter which is basically the relationship you have with a specific NPC. If the friendship meter is at an all time high that NPC will give you stuff and help you build and mine.
