Anyone who states they've grown out of the use of games seems to have 2k + posts here. THey also claim playing MMO's are useless and you should quit yet seem to stick up for their game quite often.
Just a good observation ;-).
None the less if you have spare time with nothing good to do MMO's are a good solution, it's not unhealthy. If you don't have something to do all day well play a game all day. It's not good for your health if done often however when school comes around you're going to be forced out anyways ;-0.
