Some of the "race relations" stuff in DA is quite interesting, especially comparing the attitudes of the dalisn and the city elves; and then you have Sera who absolutely rails against anything too "elfy" and even warns you off commenting about her pointy ears.
Most universes featuring humans, elves, dwarves etc involve some friction but it's usually just a very basic "elves are haughty and dwarves have Small Man Syndrome", but I felt DA was a bit more nuanced than most.
