I may get laughed out of here for posting this, but I'm kind of surprised that in this entire extensive thread, nobody has mentioned Zelda. Gorons, Zoras, Kokiri, Dekus, Sheikah, Rito, Picori, Kikwis, Twili...the list goes on, and they are all fairly original creations with few if any analogs in other works. Clearly it is possible to create entirely new races with unique traits which have little or no basis in Tolkien-esque "standards". Granted the Zelda series is known more for exploration and puzzle-solving than well fleshed out characters or dialogue, but those elements are still there to a degree, and I felt it worth mentioning.
