I find that odd, considering 90% of the game's player population seems to consist of one of the two. I can't imagine that any long time player doesn't have at least one vampire or werewolf alt. Yet once you're finished with the "initiation" quest, that's it. In fact, only once has an NPC ever acknowledged my character's affliction. That indiscriminate Dunmer vampire hunter that conveniently becomes discriminate and chooses not to kill you. Not even sure about werewolves. I just think it's a waste. Why not do a DLC where a clan of vampires and pack of werewolves are at odds with each other? Maybe because of their respective Daedric Princes. Obviously Molag Bal is out of the question for vampires, but Clavicus Vile also had scores of vampiric worshippers in Morrowind. I've come back to the game after a long break and I like some of what I've seen. I just don't get why the developers seem to be ignoring this huge area of potential in favor of much less interest content (Orsimer was just plain boring imo).
Does Morrowind do anything at all with vampires or werewolves? As in, at least doesn't just completely ignore the fact your character is one? I just got it and I'd like to check out any additional content featuring them.
