It looks like it'll be able to replace my copy of AEG's D20 Toolbox, which was my only non-Paizo "must have book" to tote around with materials.
Toolbox still has a lot more tables, so that might be an overstatement, but the tables for generating NPCs are stellar, or figuring out what a random building in town might contain, etc.
There's a bunch of pre-statted NPCs. I was actually surprised to see how many class levels some of these guys had. For example, the lowest level NPC town guard printed is a warrior 3 with 19HP. Not sure I'd drop that NPC in as a group of guards in a first level adventure, since they'd likely outshine the PCs. I'd probably end up using this guy as a captain for a small town, and use the bandit entry or something for lower-level guards. That said, I really like that there's 60 pages of this, I guess I wouldn't have minded 200 pages of pre-statted NPCs to get a wider swathe of levels.
I'm still wrapping my arms around it.
