So i had this idea, when things like sleeping have been inplented, you have to set up a camp. It's already possible in a way but i am talking about a place where you can't only warm yourself with a fireplace, but also build your own shelter with things like wooden sticks and duct tape, or a hammer, wooden sticks and nails(which would have to be implented too) maybe people will take residence in the woods, and have to build their own shelter. Or they take residence in a house and use the matress there. I tought it was a really cool idea.
