Each colonized planet in a player-owned system will net them resources over time that will be used for construction, fuel, and ammunition. Planets may be terraformed to specialize in a specific resource production type. The amount of resources produced on a planet will depend not only on its type, but the kinds of buildings built there.
The three main resources are as follows:
- Metal: Used primarily in construction and ballistic weapons
- Gas: Used primarily in fuel production and energy weapons
- Population: Used in construction and ship-based weapons
