A very interesting read, explains the fundamentals of games these days and what rule set they rely on for there games which could lead to there downfall or uprising depending on how they implement it and the attention they grab.
But you can't free all of the customers -- or rather gamers -- from their own responsibility. And their immediate environment's responsibility. I mean, like it was said in the article, it's not so much to do with the game itself, but a general inability to deal with the problems in one's life. If there was no MMORPG, then it would be another Skinner's box.
I can honestly say that in retrospect everyone I knew in WoW well enough to learn their real name and their real life story, was in fact a sad person hiding from real life in the comfy Skinner's box. It was not Blizzard doing their evil magic, it was the real world being what it is, and a lot of people not wanting to deal with it.
Replace WoW with drug and regardless, of course its the player's responsibility in the first place, but it doesn't excuse the drug, and it doesn't make it right.
A game like WoW prays on becoming addicting on common problems and causes addiction on a massive scale. Physical addiction or not, WoW is engineered to be addictive to an unhealthy level, beyond what non-MMOs rarely are. Thats much more than a lot of other "things" that can be dangerous if not used in moderation. Water doesn't try to addict you so you drink it until you die.
