High Fantasy is lord of the rings, that is classic high fantasy, Skyrim looks more like classic fantasy than OB, with the Nordic culture.
In literature, yes.
In videogames, no.
In videogames, "high fantasy" has come to mean fantasy games with bizarre, other-worldly, and/or JRPG style of art direction.
"Low fantasy" has come to mean fantasy games with slightly more realistic characters and art direction.
On the spectrum of "high fantasy game" vs. "low fantasy game", in terms of art direction at least, it sounds like JRPG>Shivering Isles>Morrowind>Oblivion>Skyrim
(In literature, "high fantasy" is any fantasy story that is not set on Earth. This has a very different meaning from "high fantasy" video games.)
