I dunno, Twistin'. Maybe those kids' attitudes are more prevalent in the USA than elsewhere, as I think your view is a little pessimistic. How can one generalise about an entire generation?
Case for the defence of younger gamesplayers: my younger brother (let's call him minicornflake) is by the standards previously described a paragon of old-school values and attitude. Has overview of gaming world; not a blinkered fanboy. Doesn't fall for hype. Never cheats. Gracious in victory or defeat. Has sense of humour. Treats games as games, nothing more.
Is absolutely excellent at anything he picks up, too!
Is he the only one like that in the world? Doubtful. Therefore, perhaps there is hope after all in this strange 21C world of mass media.
