Minecraft wiki entry for Building_a_metropolis, associated text: Empire: Instead of building just one city, build a lot of cities. Make one city to be larger than others, and make it the capital of the empire. Connect the cities with roads or a minecart network. Add smaller villages and farms outside the larger cities. If you want a more militant country, build huge walls around the borders, build many large military bases and add battle damage or wipe entire cities off the map with TNT to make it look like they were conquered.
