The Sumerian Game was developed by the Board of Cooperative Educational Services (BOCES) in Northern Westchester County, New York, in the early 1960s. The game, designed to teach sixth graders basic principles of economics, had participants play as members of Ancient Mesopotamian society. Prior to game play, students listened to an introductory programmed lecture synced to a slide projector. During the introduction, students learned about the land of Sumer around 3500 BC. Then, brief instructions were typed out for the student at a typewriter terminal controlled by a computer. What followed were various agricultural dilemmas requiring action by the player (assuming the role of Luduga I, a priest-ruler of Lagash) and progress reports on harvest and population. Random disasters, such as floods, fires, and grain rot, could occur throughout the game. Further phases of the game added in the development of crafts, trade, and other economic factors.
