video games and my brother

Video games is an obsession for my brother. He plays ALL the time. The problem is though, my dad cant tell him enough is enough. The reason is kind of complicated for a parent and I understand why my dad doesnt say anything. Chase gets extremely good grades, and along with that he has never been in trouble a day of his life. Chase does has friends but it just seems like he isn't interested in things that normal sophmores in highschool would be. When I was his age I was girl crazy and getting in trouble. Chase on the other hand stays up till 6 or 7 on the weekends not doing what I did, but playing video games. I mean Chase is a better kid than what I was but in the long run will it be better for him?
