What are the negative impacts of playing computer games? What can be done to minimize the bad effect

The reason why you asked the question above is that you heard the sound of my son playing computer games during our class, isn\'t it?^^ I think playing computer games could be a leisure for my children who were under lots of things to study. Therefore, I want to let them enjoy their leisure by doing whatever they want. I don\'t deny that playing computer games has a negative impact on my children. However, I can minimize the bad influence of computer games by controlling the time they play them. Rather, I can encourage my children to study more with computer games set as a bonus for their hard work. That\'s because if I can\'t keep my children away from computer games for good, I need to think about using them to my children\'s advantage or help my children not be obsessed with computer games.

Hi Steve. I asked this question because I\'m wondering what kind of parent you are. ^_^ I\'m also a parent so I wonder how others handle this situation.  Thank you for sharing your idea. ^_^
