I wouldn't disagree with your assessment, Outlaw, but I think you're missing some of the point of the article. The title, for example, is intended ironically, as are the references to "Halo" as a masterpiece.
It's well worth noting, however, that the subject matter of the "Aeneid" is just as hackneyed as the marines-in-space material Bungie re-works in "Halo." One of my purposes in the piece is to imply loudly that those who argue that games can't be art need to stop talking about the medium and start talking about things like the ones you bring up, Outlaw--that is, whether Bungie's re-telling of an old story breaks any new ground, and, at the same time, whether Virgil's does either.
