Once I actually got this to the table, I had to revise my opinion considerably. Here's the thing: this game's aesthetic is on point. It's perfect. But that's about the only appeal.

The setting is extremely underdeveloped. Oh, I can tell you all about the walls of The Devourer, but there aren't, like, locations. Just ideas for describing your own with the author's set of adjectives. Also, the gameplay is basically nothing. Scavenge, sell, repeat. I understand that's all there is to be done in a doomed world, but it doesn't go anywhere. The doom is perpetually encroaching, but we know it will never actually arrive, so it loses its teeth.

The system, which I first misunderstood to be very close to Lasers & Feelings, is both needlessly complex for determining the values of things, and extremely sparse when it comes to game results. The metacurrency caps at 10, but it seems like one should be getting about 5-10 from any interesting scene, so there's no reason not to spend the max five on every roll. The idea of a single difficulty number for an entire scene is interesting, because it opens the door to flexibility in your approach, but it feels like you're rolling either 1 die or 10, so any scene using the suggested difficulties either takes forever or is over in an instant.

Also, that's just my best guess. The system segments of this text are arcane. It feels actively resistant to interpretation. I can't seem to put my finger on exactly what's going on--I think the information is just presented in a really counterintuitive order? I had to go read a bit of the other games using the same engine to establish, mostly by contrast, what was going on with this one.

I can see how this could be useful inspiration when attempting to do something that looks like this, but it's less a GM sourcebook and more just a worldbuilding idea with a game strapped on. I'm giving it two stars because, as I said, the aesthetic is truly on point, and also because the artwork in the game is solid (but ultimately too sparse for a third star).
