- *Special Resources: Each tile on the map with a special resource on it will generate additional 6 wealth to your nation, building on such tiles destroys them immediately. Having the same special resource more than once will not generate additional wealth for you. In this case, you can create a trade agreement with a neighboring nation and export the excessive resources or import special resources you do not own.
- *Attacking a nation with a trade agreement cancels that agreement immediately.
- Before you make your turn, you can make a trade agreement with a single neighboring nation to export/import any of your special resources. If the agreement is still valid in your turn, you can make an action and put the agreement to effect.
