This is because of transportation advancements, which necessitate creating new houses on top of existing ones. To accommodate new citizens, you need to constantly create homes with garages such as low-rise and high-rise apartments. People need a way to customize systems such as airlines, railways and bus routes. As I mentioned above, parallel to my words, construction and management go hand in hand.

Before you can build a city, you need to start as a small town and grow into a builder.
