Games originally are entertainment. Contem-porary games are very realistic and for this reason they are a source of great experience for the player and develop the imagination. Games are entertain-ment and even more than that. The statistics (统计）of the New York University led by Green claim that the player preferring active games get improvement of some types of brain activity. In particular, game players deal with problems of simulta-neously(同时地） tracking several moving objects at the average level of 30% better than people who do not play active computer video games. The "gaming" violent experience may not be the cause of violent behavior in reality. None of the playing experience will become the priority in making important decisions concerning problems in real life. A game is an abstraction(抽象概念）. A player gets abstract tasks and acts according to abstract rules.
Games are also the possibility to be whatever a person wants to be and to rest from the outside world for some time. But what if a person gets so much excited with the game scenes that he becomes violent in reality? Then, it proves that the games cause people to become violent in reality. But a psychologically healthy person will never confuse these two different worlds. A game is a virtual world with visual images very similar to human's. These images are nothing but playing obstacles(障碍）. A game may potentially give the opportunity to "destroy the obstacles”that may not be destroyed according to the rules but it is more about personal choice whether to do it or not. This leads us to the conclusion that violence is not a consequence but the cause. People who are originally prone to violence may get into a temper by games and perform violence in the “ real world ”. But in this case violence in games is just a simple justification(正当的理由）of the violent nature of the player.
