Yep.
I've watched a few friends get lost in "EverQuest". They called it "EverCrack". Basically, they'd go to work, come home, jump into the game, play until 3 or 4 in the morning, sleep a couple hours, and repeat.
What a lousy life. (I prefer to do my living in the real world, not the virtual one...) I'd only wonder what these people would be like if they got physical feedback from a game. They'd wither away and die, I suspect. LOL!
And the undertaker will have a very difficult time getting that smile off their faces for the open-casket funeral!
