I suggest that the following becomes an option for tribe land makings. Of course, the tribe needs to do a lot of technology researching and building in order for these features to become available as usual. The following I hope may spark some idea of where I am coming from and may help make the game more unlimited and free in sand boxing:
The idea is simply this:
After building a building on tribal property, you will then be able to do the following:
1. Name it and place a sign outside
2. Design it with purposes outfitted by certain items (i.e. a warehouse by items that will help hold lumber and such or an offering box for a place to tithe or donate to the tribe.)
Design it with a purpose of being a marketplace, hotel, or something of that nature with boxing off areas and setting the amount per area that way your tribe gains money or renting houses and land for your members.
just a simple idea, but an idea nevertheless.
