CATAN - Crop Trust is a compelling scenario for the CATAN base game. In cooperation with the Crop Trust, it allows you to experience mankind’s vital struggle for seed diversity. Players balance their individual need to harvest crops versus their collective need to store seeds for future use. By harvesting too many crops, they endanger the seed diversity necessary to a healthy environment. In so doing, they threaten their world with mass extinctions and a collapse of the food supply.
