There's probably a vampire website tracking all this shit.... Buffy the movie came out probably a year or two after the Vampire RPG (movie: 1992). Anne Rice started the shitty romanticized vampire thing, but I'm not sure how the clans etc. worked in her books... I could never even get through Interview With the Vampire.
Eric, go check the 10d6 if you haven't yet--I set up a new account you can invite to the blog, which I'll then give the info to Pee-tah. It's time to get his ass back on there.
