Ah, money. There's nothing like the sound of coins clinking in your hands. Life has been good to you.
Just ten years ago, you were tilling your own fields in a simple straw hat. Today, your kingdom stretches from sea to sea, and your straw hat is the largest the world has ever known. You also have the world's smallest dog, and a life-size statue of yourself made out of baklava. Sure, money can't buy happiness, but it can buy envy, anger, and also this kind of blank feeling.
You still have problems - troublesome neighbors that must be conquered. But this time, you'll conquer them in style!
The Prosperity expansion adds 25 new Kingdom cards to Dominion, plus two new Basic cards that let players keep building up past Gold and Province, and treasures with abilities, cards that interact with treasures, and powerful expensive cards.
