A man must do what a man must do. That's the guiding principle of Ein Mann. Ein Spiel. ("One man. One game."), designed by Marcel-André Casasola Merkle and based on the book "Ein Mann. Ein Buch." ("One man. One book.") It's not enough for a man to know a few things about life, but he must also act well. At times he decides to make a difference, sometimes he must be steadfast and other times he must escape. Each man has important choices to make in his life: Will I father a child? Or would I prefer to become Pope? Perhaps both? Or would I rather give myself over to a life of crime? Am I tough, am I wise, or am I practical? Will I re-invent myself during this game? With strategic skill, the players attempt to master life, achieve goals and develop their personality. At the end of the game, they are scored.
