My nano world

It says that I control a big modern city. It states that to grow your city and discover new technologies, you need to developed different industry sectors. You have the opportunity to be a city mayor, a farmer, and a child welfare expert in the game. In order to provide citizens with all needed, you need to grow new blocks and produce other goods at the factories. The transportation infrastructure of the city should be developed. The quote is, "If you desire to arrange trade with other cities, do so." Turn your city into a mediolith of the future.
