The only thing I can say about this game is not to play it. because this game is the most addicting game ever and you won't be able to do anything else.
I am glad that I quit playing this game about 3 months ago and I am so happy that I did so I can put in some over time at work and get some work done at home.
So if you have just started playing this game, good luck on quiting it. AND if you were working some extra hour, it won't happen now.
