Is playstation is good for children? Of course we have many opinion from this statement.

At one side say the playstation is a good entertainment for children, but in otherside say that playstation is bad for children. I think playstation is bad for children, cause many harmful games in playstation can make children do brutal action, such as Grand Theft Auto and Bully. Playstation also can make children addicted, they will forget their task as student. Although children plays playstation in parental supervision, however impact from playstation to children is bad. So, we must protect our children from playstation in order to protect their future too.
