Well I won't be Praising the Vampire Lifestyle in my other saved games to stay off their radar, now that I know that I goofed. As long as they don't come calling too often I guess I can live with it. I was tempted not to save the game since I got the call from Vlad--I suspected that conversion piece triggered his call. I want to move someone to Forgotten Hallow, then perhaps I will try to play vampire interactions intentionally. I noticed that you can give them a ghoulish look when they are hunting--but can you opt for a suave one instead--maybe with just fangs. I like seductive vamps.
I don't want garlic around the house unless I have to have it. They should add Holy Water as an option and crosses to ward them off as well. I think that it would be more interesting, as someone suggested that they had a vampire hunter career track. I know in the Sim, Sims can't kill each other--but perhaps the vampire hunter can limit their powers or cure them instead.
BTW is there a cure for vampirism? I think I read there was.
