First off, I LOOOOVE WoW. But if you don't realize it ahead of time, you soon will. And it is that WoW is a double edged sword.
The good side is everything about the game.
The bad side is that once you start playing, it reaches out and links with your soul and heart, where if you stop playing, your heart will rupture and you will die. So, you have to play until WoW is content with you. So, I find myself playing until WoW will allow me to leave and scurry back to my insignificant mortal life. This is usually 3-5 hours. I'm so happy, yet scared at the same time.
Warn everyone!!
PS-If you couldn't tell by my obvious humor, this isn't serious, so don't rate me down.
