Having just finished it, I've got mixed feelings. My questions aren't answered in the end, and the central question is really representative of the book as a whole:
It's interesting, it's evocative, on balance it's probably worth purchasing, but it's just sort of ... sloppy? Inconsistent? It feels like it may have been written by multiple talented people without an editor keeping them tightly bound to a central vision, or maybe one person wrote it at a rapid clip. If you hack it apart into pieces, there are a lot of fictional gems worth using, but it seems to trip over itself in the details (or, you know, /in the central conceit of the setting/).
I'm not sure it's worth-while to write an extensive critique, but the funny thing is that that's the feeling I've walked away with: a product I enjoyed, I don't regret purchasing, but I have a laundry-list of criticisms for. And the criticisms aren't minor nitpicks, either.
I've had multiple positive experiences with +Magpie Games
in the past, so this isn't a deal-breaker, but I don't feel like I'd grab one of their books again without a few reviews first.
