It is suggested that to discourage addiction, game designers could have their games recognize addictive behavior and respond to it by encouraging gamers to take breaks. Do game designers have any responsibility to recognize addictive behavior, or does this responsibility fall solely on the gamer (or the gamer's parents in the case of a minor)?"
My son goes about it this way: Steam shows how long he has been playing his games. When he is looking for team mates, he tries to get players who spent a lot of time on the game. It is just a measure of experience to him.
