I guess if you love playing WOW, and feel it is a good game then you buy it and play it for months on end parting with £15 or whatever it is a month for an online subscription to play the game.
At the end of the day its made the way it was, to make as much money as it could, over a long period of time. More revenue to this day is probably made per person for the game at £15 a month per player over 12 months of play.
The goal of the game is to draw you in, make money from you.
Other than that what is the real world goal for you playing the game?.
Does it improve your life, other peoples lives, no. I doubt they give a crap if the game has gone down hill there laughing all the way to the bank in reality.
While the truth is your playing a game based on fantasy, if your happy with that carry on.
