The poster has what my mother always called an 'addictive' personality. It's both a benevolent and malevolent trait to have. I'm sure most professional athletes or anyone that 'masters' something to any sort of extreme has to have this sort of trait to stay intrinsically motivated.

I am disappointed to see people blaming 'this or that game' for their problems. Personally these types of folks need help and a good safety net of friends and family to point out what's truly happening instead of being surrounded by those with the same issues. Unfortunately it sounds like this guy had none of the former and plenty of the latter.
