I didn't read the whole article, because it was too long, but I got the gist. To me, it sounded like he had an unhealthy obsession with videogames, and he finally recognized it wasn't worth all that time/effort. I agree! He was spending way too much time, and games occupied way too central a place in his life. However, I think now he's just gone to the other extreme, "saying goodbye." It's not all or nothing, black or white. He has trouble finding a good balance.
Personally, there are plenty of times when I've recognized that I spend too much time playing or reading about videogames. On the other hand, I tell myself it's a lot better than just sitting like a potato watching TV, which is what most people do -- at least it challenges me, requires something of me, engages me as a participant (and in the case of forums, requires thought and effort).
I spend much less time on games than I used to, though. It's probably 5 hours a week, something like that. Sometimes none. I spend about as much time on forums, watching TV, and reading. To me, it's just one among a set of things I use to occupy or divert my attention. Other people garden, work in the yard, collect figurines, whatever. I like my particular hobbies.
If it ever got to the point where I was obsessed like this guy was, I'd know I had a problem. At least I hope I'd know.
