I voted as "I've never played it." I got the World of Darkness Rulebook PDF when it was briefely offered for free. As well, I bought some of the VtM 20th anniversary PDFs, but I've never got either to the table. I'm a big fan of Call of Cthulhu and the cosmic-horror genre, so it tends to get my attention whenever I want to run or play Horror. I played the VtM Bloodlines videogame twice which IIRC is supposed to be based upon storyteller, but having only given my PDFs a brief browse, I wouldn't no for sure. Or if it is indeed based upon it, whether like many vg adaptations it only represents a smaller subset of the rules. I did really enjoy Bloodlines and liked a lot of the flavor it implemented for the genre.
I've noticed there's official support for a few storyteller books on one of my VTT's and a robust effort by fans on the other. Which has piqued a bit of a desire to do a better read the rules. Something that's holding me back though, is that I've read that while the different books/settings have storyteller at their core, they also vary enogh that they aren't compatible with one another.
I'm a homebrewer more than anything and when I dable with prewritten settings, I prefer those that are built upon universal/toolkit rulesets. I don't mind so much when 3rd parties differentiate from one another from a set of universal core rules, but I dislike it when its done to such an exent for the same genre that mixing conent is problematic, or just not doable. I dislike it that much more when it's done by the same publisher. Admittedly, I could be ignorant enough of Storyteller to not know if that's really the case. If it is though, other than homebrewing my own content with the WoD rulebook, I can't see myself really investing in it.
The vote resultes don't seem very promising or encouraging.
