Of course, the Pathfinder game itself is kinda going the exact opposite direction as me; where I like the d20 engine at its core, I want to simplify and streamline it, and make it more friendly to my preferred playstyle, which is more narrative and friendly to GM rulings and handwaveyness of sorts in regards to system, whereas Pathfinder has gotten even more enshrouded in ever more esoteric and Byzantine codification and calcification. The Pathfinder developers (and customers, apparently) also like the d20 engine at its core, but they want it to be more complex and "complete"--more... Rolemaster, if you will.
That said, I've bought ever single Paizo Bestiary so far, and I'm sure I will this one too. Typically, the pdfs sell for only about $10, and for that price, it's more than worth it for the art and fluff text alone, even if I completely ignore the stats.
Which I don't have to do, because Pathfinder stats are still inherently compatible enough with d20 stats (and presumably my m20 stats) that I can use them without any real effort at conversion.
Also; those nosferatu vampires (publisher blurb seems to identify them) seem conceptually not unlike my Primogenitor vampires, who will be the topic of my next A TO Z post, when I get to it (with any luck, this weekend) which is serendipitously fortunate. I'm still looking for a great image for them that really does what I want it to, though that I can attach to that post.
