@TP : Did you get as far as the druid grove ? In my second playthrough as a drow I get plenty remarks concerning my origin, on first meeting different people at the grove. (Zevlor, Nettie, Kargha all comment on my race, in different ways.)
After the first acquaintce is made , my race is no longer an issue, but there are some Drow specific reactions during conversation. Not major story-altering options of course, but I get reminded of my race regularly.
I agree, it was my first time playing as a drow too and that fact was very much felt in the game. Perhaps with half-orcs really does not happen because they were not as drow in the early access, and they are still banalnano did not have time to write so much in the story. I'm curious as to how it is with drowborn.
