What are minerals good for?
A lot. For one, they are what make your basic factories work. They are also required for Titanium factories, Factory complexes, Hi-tech Factories, and Mega-factories. The amount of minerals is the percentage the factory’s base production is multiplied by. For example, a standard factory at level 3 produces 10 CP per turn. On a planet with 100 minerals, the factory would produce the base amount, 10 CP x 100% (or 1.00) = 10 CP. On a planet with 50 minerals, the same factory would only produce 5 CP. 10 CP x 50% (or 0.50) = 5 CP. And, on a planet with 180 minerals, the same factory would produce 18 CP. 10 x 180% (or 1.80) = 18 CP. Note that if you are Bionic, one bio-factory produces 50 CP at level 5 on a world with 200 environment. A ti-factory produces 50 CP on a planet with 138 minerals. Also, using a ti-factory on a world with less than 138 minerals isn’t bad … but each ti-factory require one unit of the strategic resource, titanium.
