You are a banker. You want to extract as much wealth from the world as possible--or, at least, more than everyone else. You will manipulate the global economy in order to siphon money into your secret Swiss bank account. Whoever has the most Swiss money in 12 turns wins the game.
Play solo against the AI or multiplayer against people who will imminently cease to be your friends.
Unlike most strategy games, you will never have access to armies and never directly control territory. Instead, you will spread your influence throughout the globe by purchasing votes in parliament, or selling your votes to incite a military coup. You always share power with your rivals, waiting for the moment when you can backstab them.
