You are a monarch, like your parents before you, a ruler of a small pleasant kingdom of rivers and evergreens. Unlike your parents, however, you have hopes and dreams! You want a bigger and more pleasant kingdom, with more rivers and a wider variety of trees. You want a Dominion! You will bring civilization to these people, uniting them under your banner.
Ah, money. There's nothing like the sound of coins clinking in your hands. You vastly prefer it to the sound of coins clinking in someone else's hands, or the sound of coins just sitting there in a pile that no-one can quite reach without getting up.
Getting up, that's all behind you now. 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-sized 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 neighbours that must be conquered.
But this time, you'll conquer them in style.
Dominion Prosperity Expansion is an expansion for Dominion, and must be played with either Dominion or Dominion Intrigue (or both), and cannot be played on its own.
