Villages. Can someone legitimatly expand a village by building more houses for villagers (Testificates) to breed and fill? Would these houses have any conditions to be met beyond a roof and a door?
Yes, this is entirely possibly. I keep meaning to do it myself, but haven't gotten around to it. Villagers will breed until there are .35*[number of doors] villagers. To be defined as a house, the building must have at least one block with no opaque blocks blocking its view of the sky.
