Manual:Game Mechanics/Colonies

You may begin new colonies using the colony modules (see the 'colony module' listed in modules for details on colonization). Your first colony module is at a reduced cost due to the preparations your race has been making towards settling on new worlds. The number of worlds your race can control is limited by your development aspects (Your homeworld is never counted against this limit);

World Control Limit = 2 + Level of Economics + Level of Industry + Level of Logistics.
