In the Trading Age, you will be able to trade resources for other resources with people in different regions.
At the beginning of each Trade Round, you will receive the resources that your region produced for this round.
Each resource will generate Culture Tokens. The values of the resources from the previous round will be posted.
Near the end of the Trade Round, the new values for resources (usually based upon the Crisis Event) will be posted.
At the end of the Trade Round, you may turn in resources to gain Culture Tokens.
Remember 100 Tokens = 1 Culture Score
