Sidereal Confluence EN: Profliferation expansionn

With the Sidereal Confluence: Proliferation card pack, you can add new colonies and real-time bidding to the acclaimed negotiation and engine-building game. 

These advanced colonies increase in value as the game progresses, opening up new strategies for even the most experienced players, and new bidding mechanics speed up the game while providing new avenues to negotiation. 

Sidereal Confluence is a unique trading and negotiation game where players take on the roles of nine asymmetrical alien races that have come together to form a trade federation in the Elysian Quadrant. To develop an efficient interstellar economy and an effective society, you must trade goods, make deals, and convert resources in real time!  Almost everything is negotiable, including colonies, ships, and all kinds of resources. Future trades are binding, so you’ll need to hold up your end of the bargain -- or risk a penalty. To win, you must gather victory points, which are acquired by researching technologies, using your economy to convert resources to goods, and transforming your leftover goods into points at the end of the game.
