Yeah, there's definitely a lot of metaplot stuff buried in here. Not sure how much use most of the rest of the book is, though. Its a lot of fiction and IC talk about Orks, Trolls, and the organizations that focus on them (for good or ill). Which is interesting, but most of them are pretty well known (MoM, Sons of Sauron, Paladin Medical, Human Nation, etc. The Sweetwater corps are cool and might be useful if you want to run an trog focused game in the CAS.
I am sorely disappointed by the lack of information expanding on the troll and ork metavarients. There's brief mentions of them here and there, but that's about it. And even then, its usually just a name drop. There's no guidance on how it might be different being an Oni or Satyr than a "regular" Ork. Even though Goat Foot and Mihoshi Oni post, neither of their metatypes are even mentioned in the book as far as I can tell.
There's a few bits of gear, but most of it is just "ooh, a troll sized version of something that already exists."
I've been playing SR off and on since 1st edition and I own nearly everything for 4th and 5th edition. This is one of the few products where I doubt I'll ever look at it again after the initial read through. Its not bad quality material. Its just very little that's new unless you like stats for NPCs like Snopes and Sunshine.
