I played Everquest II and WoW for a long time. However I realized how much time I was wasting playing those, espcially EQII since the questlines and raids take soooo long. I really loved EQII though because I got addicted to finishing those epic questlines with various toons.
I am considering trying out Lord of the Rings online just to have something fun to do, and try not to get addicted to it
