well it depends on how many races we get.
I guess races like gith will, given the nature of the story, be given some love.
I dont think that a Duergar will get a lot of specific responses.
Personally i hope drow will be handled like undead in OS2, maybe also tying into the Reputation system. so instead of it beeing a trivial nuisance like in OS2, it would eb an actual risk factor
