Skyrim is considered by most to be one of the best fantasy RPGs ever and I can kind of agree with that (I still love WoW and would take it over Skyrim if I had to choose just based off lore alone).
If you could have any race(s) added to the next Elder Scroll Game (hopefully better than ESO)?
Personally, I like the idea of a bovid race (different from tauren), but again that's just me.
