You will have to go from planet to planet to expend your empire to exploit the resources of the planets but don’t forget that the resources are limited and will affect your economy. Moreover, when there will be no more planet to colonize, your only way to gain resources and wealth will be to become an imperialist and conquers the planets of the other empire. You can also create your own campaign with an editor. You can play alone or with friends and even cooperate by trades or playing the same player.
