Colony structures

Colony structures are the basis of an empire, improving various areas of their functioning. All structures are categorized first by the area of a colony's functioning they affect, then by the type of bonus:

• , , , : bonus to the planet's output
• : bonus to farming
• : bonus to industry
• : bonus to science
• : bonus to taxes
• (SYS): bonus applies to entire system
• (EMP): bonus applies to entire empire
