Person depends on game away from them. It can be aggressive, or it can be frustrating for the real world. With such a person, it is difficult to make friends.
In my opinion, a person which is addicted to computer games can't stop form playing. Most of all, that kind of person is usually unconvinced in bad influence on his brain. He, or she is loosing touch with surrounding and with family members. I am sure it's worst addicion of all.
