You can buy houses or you can also kill a houseowner and take his/her house. And this time you can actualy sleep in his/her bed. So no more "You cannot sleep while trespassing".
Quote from Todd Howard:" If you want, you can kill everyone in village, that was "two barreled thing" to us. Everybody begs for that feature but eventually they won't use that. And that's annoying because that takes much of our time. But the feature is now in."
So thats it. Sorry if these were mentioned before
