Individuality is easy to see in game. During game there is a sense of liberty; the individual must not conform to the rules and normal laws which rule the physical and social world. A person can play in a sport team, be an Olympic athlete, travel on the Moon. The real world's limitations are removed in the player's mind. During the game can be a "temporal exceeding of the distinction between real and unreal, true or false".
