For example a tiny mining colony does not have to be a full city in order to do mining for other cities in a solar system.
When buildings are part of a city or a base, a lot of extra requirements and overhead is added to keep the population happy and alive. For example a city with a population of more than 45 will start to require morale buildings, which will take time and resources to construct.
- ... does not require morale buildings.
- Especially useful for tiny worlds with tight volume limits.
- ... does not need food or air to keep population alive (needs confirmation).
- ... does not clutter the Cities and bases list.
- ... reduces the visible number of cities listed on the star map.
- ... cannot have a capitol for easy management.
- ... cannot generate a city report.
- ... does not appear on the Cities and bases list, making it easy to forget.
- ... cannot have a bank to mint money.
- ... cannot send shipments.
- ... will not be able to show nearby reveal nearby alien cities on the star map.
A colony normally need the following:
- A trade connection
- Operation buildings
- Power plant
- Enough homes to cover all jobs
A power plant might not be required for the colony to work, but it allows the colony to be more efficient and work at night if it is a habitable environment. If a road connection can be established to a power plant elsewhere on the world, the colony will not need a dedicated power plant.
