Bottom line: I have yet to see traces of High Fantasy (a la JRPGs) in SKyrim, getting back to the OP.
http://en.wikipedia.org/wiki/High_fantasy i think tes incorporates many of the features that make something high fantasy it is set in a completely different universe and its plot usually involve epic battles of good vs evil se to the backdrop of a cataclysmic event, i dont think all JRPGs can be labelled high fantasy either as one JRPG can be quite different to the next
