"Economic civilizations use cash and trade routes to influence other nations. They'll form alliances, but it's usually a better deal for them."
Economic Consequence Abilities
Spice Savant: "This ability increases spice production from all your colonies."
Gaining The Economic Trait
The economic trait is gained by purchasing cities through the Trade of Spice. It is possible, but difficult to gain the trait if you didn't start out as an Economic nation; as these nations appear less frequently during Civilization Stage, and other nations often destroy these nations shortly after they start out. This is the most peaceful way of capturing cities, but it can be expensive. It also poses the least threat to your nation should trade fail.
