Excellent stuff! A briliant starting concept - and an excellent execution, which shows a remakable understanding of the original Vampire - The Masquerade setting / worldview as well as of the relevant game mechanics. By de-emphasising the all-encompassing, all-devouring "crossover" aspect of the World of Darkness and focusing on the in-game perspective of VtM (as opposed to the WoD "in general"), this well thought-out variant brings us back to the original spirit of the first "storytelling game of personal horror".
It is a must-read for anyone interested in running a classic Vampire The Masquerade chronicle - especially at such a low price.
It would also be very interesting to apply the same concept to Mages (or would they be "sorcerers" ?) or to reverse it (re-imagining Vampires as opponents in the context of Werewolf the Apocalypse).
