I think so.
Though I've been addicted to a few games to the point where I would go days without sleep, in games such as Elder Scrolls 4: Oblivion, Warcraft 3, and Zelda OOT, so I can see how it can start to ruin peoples' lives if it persists.
I.E. My cousin. He deleted my character in Oblivion.. -_-' Was ready to whack him over the head.
Luckily though, I'm home schooled, ftw. So game addictions are something I can afford to have.
