Each planet has 7 associated stats and maybe some additionall resources. These are:
-Size: How much buildings can be constructed
-Population: This is limited by the amount of food you have. Changes in pop will not be instant. Pop is needed to work in buildings.
-Industrial capacity: This resource is used to construct things
-Science: This resource is used to construct things
-Energy: This resource can be easily used as a currency, but is also used to power spaceships.
-Ecology: This stat reflects the overall health of the planet. Best is to keep it as high as possible. Bombardements, and other actions also lower it. Some natural structures on the planet regenerate it, qnd with the right tech you can reunivate your planet.
There are a variety of buildings that can be constructed on a planet. These are:
Population
-Farm: 1 IC, 1 size. 1 Pop workforce required. Produces Ecology/20 food
-Improved farm: 2 IC, 2 size. 2 pop workforce required. Produces ecology/10 food.Industry
-Mine: 2 IC, 1 size 2 Pop workforce required. Produces 2 IC/ turn. Lowers ecology by 1 for every turn in operation
-Industry: 6 IC, 4 size 4 Pop workforce required. Produces 4 IC/turn . Lowers ecology by 1 per turn in operation
-Improved industry: 8 IC, 4 size, 5 pop workforce. Produces 5 IC/turn. Lowers ecology by 1 per turn in operation-
Nanotech Fabrication: 15 IC, 4 size, 4 pop workforce. Produces 6 IC/ turn. Warning: Only you can prevent Grey goo. Science
-Lab: 6 IC, 2 size, 2 pop workforce required. Produces 2 science points per turn
-Large lab 15 IC,4 size, 6 pop Produces 6 science points/ turnEnergy
-Fuel refinery: 4 IC 2 size, 2 pop workforce. Produces 2 energy each turn. Lowers ecology by one
Utility:
-Observatory: 2 IC, 1 size, 1 workforce. Allows you to detect all motion in your system and do remote exploration
-Artificial pollution Filter: Size 4, 4IC, removes 1 pollution -Hospital: Size:2, 6IC, 0/1 pop. Increases soldier heal rate, increases pop growth -Small spaceport/Shipyard: 5 Ic, 2 size, 2 workforce Allows you to create ships with a max size of 40, as oposed to the default 20
