Lack of voice acting for your character... although I know with the sheer amount of conversations n things in there, for all the player character options... would have been an insane job to put it in but still... to hear all that dialogue and then my character being a mute during conversations... I dunno, its a small immersion breaking point for me
Oh but (as contradictory as this may sound) hearing my dwarf say "I shall do it!" for the millionth time gets frustrating hehe
