In this ingenious strategy game it is not the players who take turns, but the six major powers! The players are just internationally operating investors who act in the background. By giving money to the six powers, which all have their own treasuries, the players influence the politics. The biggest investor in each nation gains control of that nation's government and decides what the nation will do. As control of a government can change with each new investment, players may control several governments at the same time. As investors, players should not get too attached to their preferred nation, but rather focus on where their investments have the best rates of return. Essentially the game is about money, and not about military domination!
