Game
Game is an activity that usually involves more than one person, subordinate to some rules. In contrast to the play (which is a pleasure in itself), games have some goal sometimes set in the realities of competition with others. In development function games are used as mechanisms for: learning in simulated reality (simulation), engaging and motivating through competition, building motor skills (e.g. team sports) and psychomotor skills (e.g. playground game), etc.
