calm down fanboy, he wasn't saying it was a bad game, hes saying he don't want to get addicted.
seems like a perfectly reasonable, responsible reason to not play.
You can get addicted to any game, though.
All MMO's have their share of addicted players. I would say that out of all the MMO's that WoW is the most well known. Because of this, more people see what WoW has done to some people, and, therefore, the majority of those people assume that if they play the same will happen to them. Even people who don't game at all know about WoW, and all their views of the game and those that play it are the same.
