Video games can sit at the social crossroads of parenting, adolescents, trust, autonomy, values, culture, and adulthood.
Because of this, there is a tremendous variation in the ways families and people approach video games. Some families might be very liberal, some might be quite conservative.
I always thought good parenting is about the right balance of letting go and holding on, and like our immune system, kids need to be exposed to society in order to learn how to deal with it.
