This is an Austrian Economics card game. The key learning from the game is that prices communicate value and - in truly free markets - they are determined by individuals. In truly free markets, prices are not determined by central planners, government bureaucrats, tech companies or politicians.
The theme of the game is futuristics. Ever want to buy a flying car? A time machine? Now you can. It's a future market where you will find shrink-ray guns, robo-dogs, anti-gravity boots and other fun technologies. Players alternative buying and selling items. There is no one right price. Each interaction is its own negotiation. Get creative! And, if all else fails, just ask, "Is that the best you can do?"
