Dr. Jerald Block is an Oregon Psychiatrist who deals with gaming addiction, an ever-growing and, according to Block, under-recognized form of addiction with complicated pitfalls for treatment.
World of Warcraft addicts, for instance, have a hard time getting treatment because of the language barrier between the therapist and the patient as many psychiatrists have no idea what a guild is or what it means to advance in levels.
Even more interestingly, porn addicts feel less shame when addicted than WoW fans.
Block says: As a society we understand that porn is something people do, and you can see a psychiatrist and get treated for it. But gaming is hard to describe to anyone else. So these people can't explain their situation to friends. In fact, it's hard to give you an example of what my clients talk about, because gaming is enormously complicated.
Also, Jack Thompson apparently gets the first comment on the Game Politics article, and if that really is him, it shows how delusional and computer illiterate he really is.
