Category:Cities and Colonies

Cities and Colonies are very similar, the only real difference is that cities are open to the environment while colonies are self-contained.

Cities are usually immense constructs with large buildings and an immense, dense population. They are often semi-automated in more advanced civilizations, but are generally based on a central city hall or main street around which the city was built. There *can* be towns and such around it, but as a civilization gets more advanced cities become denser and the populations gather in them. In the most advanced of civilizations, cities may not even interact with their planet, though most civilizations interact with planets for food at the least.

Colonies, on the other hand, interact with their planets in that they cannot exist in the natural environment of the planet and are therefor self contained. Examples are Star Cities, Lungworlds, Asteroid Colonies, and Moon Colonies. They are usually harder to upkeep them cities, due to needing food/air/plants from an outside source, but can make an immense amount of resources for an empire. They are often used for mining colonies or to house excess population.
