The genesis of the simulation video games extends from the early 1950s to the 1960s, decades during which several computer programs of military, and economic simulations in the civilian, are carried out, in particular by the Rand Corporation, a research center working For the armed forces of the United States. Originally, these games allow the army to test its strategies or train its leaders in the management of armed conflict. Some are notable, such as Hutspiel in 1955, or the series of Sigma simulations served in the 1960s during the Vietnam War Conflict and the most notable of which are Sigma I-64 and Sigma II-64. They arouse the interest and creation of economic simulations in the civilian field, such as The Management Game in 1958, created by Carnegie Tech in Pittsburgh. If many documents concerning other precursing creations in this field since the end of the 1940s have been found, these simulations are however not accessible to the public and it is difficult to obtain informatio...
