well, custom houses can be done outside for the builder, so they can just have empty lots in the city, so you can chose from a pre-made house with no building fee, and a monthly rent, or one with a building fee, and a monthly rent, these rents are taxes, you know, property tax, that way, one person cant occupy a house forever if they don\'t constantly work for it, however thats why you dont have to pay for one outside of the city, because no property tax, because its not part of the city, but there are no premade houses out there, and as said before, its not as safe....
Edit: And I would restrict barracks to guilds only, dont want some HUGE amount of barracks sitting out there, it would ruin the feeling, so when you do see one your like, \"I dont wanna go near it\", Instead of it being tightly packed with rich players with their own barracks, I just want them to appear rare, and possibly frightening.
