See, you all don't get it. It's an analogy on the farming industry. First settlers with little money would come and plant seeds and make tiny profits. Then as they grew, they were able to buy newer technology use more land and be able to raise animals. As time goes on, the farm became very large and very profitable. In the end, cities would grow and the farmer would sell his land so that people could put their houses on it and create new suburbs for the city. Incredibly deep game.
