All values are based on a planet with its resource value at 100, such as 100 Metal, or 100 Gas. Planets with lower values will produce raw materials slower. For example a planet with 50 Metal will produce Iron at a slower rate than a planet with 100 Metal

If a building can produce more than one thing, it must be manually set to the resource you want. For example, a Mine can be set to produce either Iron or Copper, but not both at the same time. Each building, even if the same type, can have a different production chain, not all mines have to be identical! You also manually set the production target when a resource can be created in several different ways (for example Steel)
