game design hypothesis: I think in TTRPGs, mechanics and narrative might be something that exist on a sliding scale that I can imagine like this:
Narrative [-----X-----] Mechanics
You can move the X left or right and stretch it a bit so it covers more ground, but you can't just decide that the X is now so wide that it actually covers both sides of the scale.

I got Eat the Reich only a few hours ago and quick-read it once. Here are some early impressions:

1. This is about the maximum amount of Art and Design you could possibly expect from any book that is still required to use text to actually convey information to you. There is no default page. Even the few text-heavy pages look like different documents every time instead of a template. And they are few. There's always art, there's always new design elements, this is elaborate as fuck. You want to show this book off. And it doesn't really contain secrets, so you can.

2. It both opens and closes with extensive tone and safety tool segments. Which both makes sense for this subject matter but should maybe just become the standard for all publishing. I would like if (and I expect this to take 15 years) regular novels just have a final page that says, by the example of this one "This book heavily features: Blood, Antagonistic Fascism, Vampiric violence. It implies but doesn't highlight or depict the many war crimes of the third reich. It does not depict violence against innocents." If you want to make sure you don't have to read a book with blood in it, you can always check. If you don't want to know: That's why it goes on the final pages of the novel.

3. The game is SO clear about what it wants you to do and how to do it. It's never in doubt about theme, pacing or energy. All Blades in the Dark likers know the anecdote where the author supposedly expects the game to be very fast-paced, but many people take many sessions for one mission. Because the game doesn't say. There is not a single word about the intended length of a mission, or how to scale difficulty if you do go long. Which is acceptable. But Eat the Reich doesn't just answer questions like this once, it clarifies its ideas often (and from different angles, not by repetition) enough that I got it while skimming.

4. I suspect this game is close to a pareto optimal of design. Again, this is a first glance impression, but right now I don't think there is any easy change you could make to improve something, without making anything else worse. It is a short read, small, extremely art-filled, still very readable, not very expensive (besides import cost), optimized for fast play and easy to understand, thematic and clear.
   I can point at most RPG books I own and go "well this could just have more art" or "this could have been so much clearer" or "I would have liked this to simply open with a 'what's different from all the other hacks of this system' segment so I don't have to read all 80 pages that are otherwise the same" and just none of that applies here at first blush.

5. I bought this by googling "eat the reich" and then getting what came up as the first result. It turns out, they also sell the character sheets. But you have to go back on the website to find out about that. There is no "would you like this in a bundle?" somewhere on the first Eat the Reich store page. So I'll have to print out pages of the PDF at the print store. This is just to help readers possibly dodge this same mistake.
