Play is the main activity performed by children with computers. According to studies conducted in 1990 in the United States and the United Kingdom, children spend an average of between 25 and 45 minutes per day playing video games. Electronic games have existed since the 1950s, and became a mass market for 1980.
Like all games, electronic games have a goal, obstacles, resources to help pass the obstacles, rewards, and sanctions. Awards are generally new resources, while sanctions are either loss of resources or new obstacles. Electronic games are characterized by the presence of a competitive situation, luck, altruism or extravagance.
Many games make use of virtual reality techniques: The purpose is to give the impression that a person is actually within an environment as it is imaginary, artificially created. This giving him the opportunity to see, feel and control what happens in this environment.
Increasingly popular computer games are often criticized or denigrated for sexism, gratuitous violence, antisocial appearance and anti-educational. Electronic games are now part of the convergence of modern media: the book becomes film and the film becomes electronic game and the style of the game is used in music and the arts graphiques.
