I don't think I'm "addicted" to The Sims (or any game I play for a high volume of hours), because that implies impairment of function outside of the game world.
I don't have much of a social life, but that's not because of "too much time gaming". I'm autistic. Functional enough to hold a job and live independently, but I can recharge my social battery completely independently of human interaction and am far happier alone than with all but the closest of friends.
So I play a lot—I can easily burn 30 hours or more between Friday afternoon and bedtime on Sunday—but it never comes close to qualifying as addiction.
