From the campaign:
Ever wonder what it would be like to lead a nation in a world where you and your friends were the rulers? In Manifest Destiny, you and your friends have complete autonomous control over your own empires. Lead your nation through conflicts with your friends over resources and territory, or dominate the board economically. Construct the nation you've always wanted, and lead it to victory over the other players!
Delve into the complex world of diplomacy, economics, domestic policy, foreign affairs, and war. As time passes, watch your young country grow into a mighty empire. Move your citizens into new territory to extend your country's boarders, and increase your nation's control by demanding more land!
