Its not good. And I think part of the problem is the odd set of values or whatever that this person...and many similar that I have encountered...set up for themselves.
Part of why I empathize is because I am getting a feeling lately that a lot of young people are just so barraged with so much crap they cant think straight. People get stuck in absolutes, and in unyielding ideas, instead of 1) trying to understand others while simulataneously 2) realizing that you cant understand everything, and some times you dont have to.
Its about compromise, and understanding things.
But we do live in a culture a large part of which is hostile towards those who have and use imagination, and/or who are interested in "higher" pursuits than the making of as much money as possible or the drinking of as much liquor as possible, or screwing as many people as possible etc.
I dont think having a monomanicial obessession is the problem in itself with many "sterotypical gamers", I think the obessesion is a symptom of other issues.
