I don't mean just the unique dialogue options that your character can do though. When I play my Githyanki character so many people in the grove responded to that, usually just little things like not knowing what the hell I was. I remember Guex (The Tiefling trying to practice sword fighting) even completely stumbled on his words when he looked up at me and then apologized for it because he had no clue what the hell I was. I just thought it was funny. Not to mention Lae'Zel and Shadowheart responded entirely differently to me too. People respond to my Drow character a lot too, because they dont see them much and are wary of them. Playing my Dragonborn I figured there would be SOME comments, but... nothing. I just cant imagine they see any more Dragonborn than they do Drow. My interaction with Volo went a little different, especially when he got to his 'what kind of dragon was marching at the back' question and then seemed to realize what he was talking to. But that's been it. Its just those little details and tweaks in interactions I find immersive and fun to explore in subsequent playthroughs and when its missing it makes me sad XD
