Addiction is a tough topic, and WoW is an easy sell as a scapegoat. Like any activity you love, if you feel passionately about it, you should fight for its proper representation. Jace certainly is.
His stance on addiction:
Hall laments that news organizations and personalities seem eager to paint activities they're unfamiliar with or don't understand, like WoW, as unique and dangerous forces in addiction then countless other activities. Among those with addictive personalities or social difficulties, any activity can become addictive, and this particular report, he says, is pure fear-mongering "based ultimately on conjecture.""It is my opinion that human beings are capable of creating destructive relationships and associations with almost anything. Seeking pleasure and avoiding pain is a fundamental trait of the human condition. This trait can occasionally direct people toward the use of escapism. Sometimes this can be a necessary mode of survival and very healthy – other times is can lead to counterproductive personal and social behavior.
What that means is that, YES, someone can get so involved in watching movies, or reading books, or tweaking their myspace page, or surfing, or playing games, or swimming or drinking, or using drugs, or having sex, or ANYTHING THAT THEY FIND USEFUL TO ESCAPE WITH, that they actually begin to ignore other important aspects of their lives and it becomes a real problem."
My personal opinion on these matters is that it's difficult to pin "WoW addiction" on any particular source, and that usually, like Jace says in his article, there are circumstances that extend far outside of the game that can cause these problems.
