Confirmed, WoW is a great MMO. I actually had to quit because I was too addicted. I believe 10 - 14 hour sessions constitutes addiction. I was in a guild of 100+ and when I joined, our highest level warrior was at about lvl 27 or so. By the time I quit, I was the 2nd highest level warrior, 3 or 4 levels below him. I logged on a little more than 10 playing days within the span of 3 weeks. Thats ten of 21 real life days devoted to a game.
And I loved every minute of it.
If you decide to play, I suggest Uther realm. If you're Alliance, look for Ring of Valor. They're good kids. Tell 'em Goodlovin sent ya.
