Caveat: I don't like V:tM or V:tR or WoD or anything related. When Venger said he was going to write an OSR heartbreaker based on them I came up with a very involved arguement that involved waves and cycles to show that the Storyteller games couldn't be Old School until 6e D&D comes out.
Turns out I was wrong.
BDT works as well its own thing and, if you're less lazy and burnt out than me, would be a perfect stand alone game for as much material as you can squeeze out of it. To me it does seem to expect a basic knowledge of the WoD stuff, if only to deliberately ignore it. You can get workable characters out of it in about 15 minutes if you're distaractably watching YouTube videos. If you have no intention of running it directly then there's plenty of ideas to drop into your other OSR games.
My only real complaint is that it feels unfinished. Like I've only got a third of a final game here. Hey Venger, if you ever do expansions for Werewolves and Sorcerers then let me know. Meanwhile I'll be over here not publishing my own osr style paranormal/occult heartbreakers. With blackjack and hookers. (Although I'm struggling with the blackjack based task resolution system. And the hookers are expensive.)
