The history of games dates to the ancient past.[1] Games are an integral part of all societies. Like work and relationships, they are an expression of some basic part of the human nature. Games are formalized expressions of play which allow people to go beyond immediate imagination and direct physical activity. Games capture the ideas and behaviors of people at one period of time and carry that through time to their descendants. Games like liubo, xiangqi, and go illustrate the thinking of the military leaders who employed them centuries ago. When archaeologists excavate an ancient society they find artifacts related to living, working, family and social activities, games often become an archival record of how individuals and groups played in earlier times.
