Okay, that's more like it.
I found the NPC Guide something of a letdown: a bunch of midlevel characters, mostly human with the occasional elf or whatnot, and just... not all that. Also, I truly wasn't interested in meeting the Paizo staff characters.
This is better. Ten NPC adventuring parties, ranging from APL 3 to APL 20. Most are evil, but some are neutral and one is good (but with motivations that make them plausible rivals or at least annoyances for PCs). Also: a sprinkling of new game content -- a few feats, a number of spells, several magic items. Not too little, not too much, and the quality generally high.
The NPC Guide left me so flat that I very nearly didn't buy this. But I'm glad I did.
What think you?
