I don't know if any ever played the game. I did for the past six months. In that time I have spent $850.00 on in game "gold". I missed a house payment and had my electricity shut off because I spent the money.
My wife and kids begged me to stop because I was playing 6-8 hours every day.
I work in IT. I would spend my work hours surfing the game forums, often putting off my work.
Often during work and family events I would drem about my next "battle" and how to come up with real world cash to buy things in game.
I had no idea it could get this bad.
