Here is a brief description:
You are a merchant in Ancient Greece. You control a small group of workers who have been hired to trade your goods in the market on the island of Kos. The three goods available in the market at Kos are: fish, olive oil, and wine. In order to trade, your workers must first set up stalls in the marketplace. Your workers must then try to maintain control of these stalls while attempting to control stalls placed by the other merchants. Scoring takes place at the end of each of the 4 rounds. You receive market points for laying stalls in the market, for having the most influence around a stall, for moving your workers, and for influencing different unique stalls. The merchant with the most market points at the end of the game is the winner.
