just imagine what your life would be if the bazillions of hours you spent "playing video games" had been used to educate yourself to improve your salary and quality of life.
while you re "playing video games" someone is learning, achieving and basically moving on into adulthood and responsability.
Kids play videos games - and they shouldnt, they re getting addicted very soon-. Adults dont.
Video games are an addiction, and a business that weighs billions of dollars a year. It's a fairly recent phenomenon so we still dont know the side effects on a large scale.
