You start with a tract of land. People visit and you get a house. There's farming. Hay is involved. More people visit and more houses pop up. Eventually there's a store or two, then some industry. Then the roads get a little clogged, and someone opens a gas station. Next thing you know the whole place is crammed with angry people, a Starbucks on every corner, and buildings that stretch higher than the eye can see.
