they would be present as NPCs, companions, enemies etc. Which totally ruins immersion.
I ... m affraid i dont follow, how can race that (even tho rarely, since there isnt much of them) but still naturally occur in the world can "ruin immersion". :-/
Ok, you dont like them, you dont like to meet them, you would preffer if they wouldnt be here at all ...
That part i get.
But why talk about immersion, especialy since its so obvious that this is just an excuse? :-/
