Forgot to answer OP. If you enjoy supernatural stuff, I'd say vampires is probably worth your time, but if you're not really planning on creating a lot of vamp households I'd probably say pass on it... I buy every pack, even if I don't necessarily want or need it, I just like to have the most up to date collection. That said, there are definitely packs I'd recommend bypassing if you're needing to be selective, and for me I'd skip vampires - I think I've made one vamp since the pack came out.
