And in Dragon Age, Elves have more or less the same role as Khajiits and Argonians have in TES: They are viewed as lesser beings, and the city elves live in a poor ghetto, where they are harassed and even [censored] by the high and mighty human lords. So my point is that on the surface, high fantasy is all "cliche", because they use the same building blocks and same elements. The uniqueness lies in how they use these elements. So TES isn't more or less unique than other high fantasy books/games. They all are cliche, and they are all unique. Being a fan of one franchise, it's easy to view it as "better" or "more unique" as others, when they are actually the same (but different).
You'll notice I said nothing about Dragon Age. I rather like their portrayal of elves as the outcast and downtrodden, though its hardly like the Khajiit and Argonians (I'd compare them to the Orsimer, if I had to).
Something which is cliche cannot, by its very definition, be unique. A cliche is "expression, idea, or element of an artistic work which has been overused to the point of losing its original meaning or effect, rendering it a stereotype, especially when at some earlier time it was considered meaningful or novel." Unique, on the other hand, means "being the only one of its kind; unequaled, unparalleled or unmatched." That is precicely why I used generic, as in "pertaining or appropriate to large classes or groups as opposed to specific," rather than cliche. What you mean to say, I think, is that all fantasy builds on the same tropes. However, uniqueness comes from how it differs from the trope, and it is still possible to say that something is "more unique" than something else. TES and Dragon Age's elves are certainly more unique (different from the norm) than the elves of D&D and its related universes, which have been been recycled by countless other IPs.
