Even the upstanding-moral-exemplar heroism?The thing you don't realize is that all D&D is Gen X. We were the only ones allowed out completely unsupervised, riding our bikes wherever the winds took us until the streetlamps came on. We drank from water hoses, rode in the back of pickups and station wagons without seats much less seat belts. We raised ourselves. And like adventurers, the ones that survived became mighty.
Because what you just said, to me, screams Greco-Roman heroism. The kind that exalts the potent, not the principled; the mighty, not the moral; the proud (in both senses of the term), not the painstaking. All of which fits rather better with the "Question Authority" vibe of Gen X. (Well, other than that Greco-Roman heroes are always a half-step away from hubris...though even then that isn't THAT far off the mark.)
D&D's original, Gygaxian roots were definitely that. But the direction it almost immediately swerved was toward knight-in-shining-armor tropes, Big Damn Heroes, etc. Three Hearts and Three Lions is a huge influence for a reason.
