I agree with sime folks here and some I dont. WOW is very addictive and you can listen to some samples of freaks that can stop when their parents tell them to stop ect. So, my advice:

Stay away from Multiplayer Games, they last forever however you get sucked in, you make virtual friends, get really fat and waste your life away.

Stick to single player games, play the game and love it; and when you finish you may even play again, however when it ends it pretty much over and you can continue with your life and family.

Single players are simple to pause/save and walk away from, WOW is insanly addictive and will suck you in like a bad falling dream

SO.... WOW is very fun, however I speak from lifes expeirance back when Diablo was consuming my life. Stay away from things that give you this in the morning:

"I just played for 12 hours yesterday, and I achieved level 12.I wonder if my girlfriend will call me back after i yelled at her for letting me die (in character), and my mom is still pretty pissed cause i havent called for 4 days. ...wow, am I getting fat? "
