I never got into WoW, but I play another one, and I'm often playing with people who are in and out because they're actually at work.
Also, my SIL and hubby got into an online game that's meant for younger kids -- she was playing constantly at school during free periods!
What game do you play? Oh wait..is it Runescape?
And Fat Spartan. Trust me it is addictive, once you play the trial version you will realize that it is not just one game but it is one game with many things to do. Ofcourse when I'll get tired of that I'll think of something else.
I am not ganna force anyone but do give a shot to 10 day free trial to see how the game actually is.
Playstation 3 online is free. By the way.
