Just sounds like all the usual crap. Kid gets in argument with parents, probably one in a long string of arguments, this becomes a last straw moment, kid runs away, non one questions the parenting skills of his, ummm... parents, and everybody blames a video game.
I mean come on, doesn't anybody wonder why the parents of the columbine shooters never were interviewed, because the whole thing probably stemmed from their crappy parenting. But no... no one ever blames the absent parents... noooo it wasn't their fault, it was those damn video games, just like comic books and rock 'n' roll in their hayday.
