I don't see it as too bad, personally. When my mom tried getting all bent about it when I was in high school, I pointed out a few simple facts. I didn't smoke, I didn't drink very often. I came home when I said I would, and I had a job to pay for my expenses. Mostly though, I wasn't out getting in fights or getting every sophmore girl in the school pregnant. There are worse things to be addicted to than video games. (And no, I wasn't a shut in. I was also in a garage band.)
