torn hare
a new block called a "town Center" that will spawn civilian NPCs around it.
their purpose? doesn't have to be anything at the start, can simply wander aimlessly around your base at first that way it doesn't feel so depressing when your playing by yourself, that i'm okay with.
but if you want to go all out, would be cool to have mechanics for it like each bed you place can spawn a Civvy, and things like benchs, bookshelves, chairs and rails they can interact with,
like perhaps finding a 2 block high wall they can lean on and look over, maybe when their code wants to sit, they find a single lone block.
even further more you can make crafting stations for them, mining outposts where you can draw a 3d blueprint of what you want carved out. forestry station where they plant and chop trees in a certain distance.
