Dominion Prosperity - Expansion
Released in late 2010, Prosperity is the 4th addition to the Dominion game family. It adds 25 new Kingdom cards to Dominion, plus 2 new Basic cards that let players keep building up past Gold and Province. The central theme is wealth; there are treasures with abilities, cards that interact with treasures, and powerful expensive cards.
This expansion requires a base Dominion Game which is here.
