I agree with buzz, except there's no 'at this point'. It was its own genre from the off, a kitchen sink blend of Tolkienesque world, Lieberesque adventures, a Vancian magic system, etc, etc.
Bingo. D&D is a kitchen sink kind of flavor. And I think that "Game Fantasy" is a good term for the genre, because a lot of games follow it but almost nothing written does. Though it is a union of many written genres, so it has the ability to briefly dwell in those tropes, sooner or later it will fall apart by the demands of the game and the fact that it wasn't really meant to.
