Your in my city, and your in one of the gamemodes, and whatever area your in, it will show what number area your in, and, or what is the name of the area, and it will tell you what district your in, also whatever borough. You can also see that when I build two maps next to each other, they will have the same layout, no changes (except for updates). I will make a map(drawn) of the city in a couple of days or so. Also, to straight out the areas, districts, boroughs, I came it up with like this:
Area: The Part of a District, and Small.
District: The Parts of a Borough, Medium sized.
Borough: Large Size, takes over one part of the island.
This will show you how the areas will be organized in my map.
He didn't mean literally how it works, just how putting it together is coming along. :/
