I haven't read all this yet, so maybe he touches on it. The point about interconnecting pieces or like "gears" that are all involved is a good thing. Everything is dynamic and in interplay.
A lot of that means these are not linear systems (not in a systems theory sense, but textual sense). Graphics and images do volumes. But only so much as you understand, again, the WHY. Everything has to feed into the "economy" of the game and how all the parts interact.
Rulebooks also need to make sure terminology is consistent. I've played some games where I see a word that's used, and then I try to find the definition and it's just... not there. At least not easily found. An index of some sort is necessary if you're going to use special terms that aren't obvious (and if they are obvious/standard words, but you use them in a unique way, also define that).
I think there should be: 0. Intro/thematic vibe/core concept - the what you are trying to do and possibly why. 1. Component Overview - the what you are playing with. (Include a layout of the setup version of the game). 2. Step by step rules, underlined words that have specific definitions to be referred in the index. 3. Examples are ideal (including images), especially in tricky situations that involve edge cases (or worse, corner cases) 4. Common "edge cases" (oxymoron?) that are trickier should have their own FAQ/addendum for clarification. 5. Glossary/Index
Rules should not try to be cute and invent words for common scenarios unless it's clear what it means in context.
Rules should NOT try to be super thematic. A little flavor text at the beginning is fine, but like the above issue, there should not just be things like "Grippledize the phlumoxor to gain 10 boodiboos" Just say "place your character piece at location 3 in order to gain 10 units of currency" or whatever.
If you're going to use terms like that - use them on the cards as flavor text, not hinge the rules on understanding them; or if you're going to be cute with names, be consistent with it, and constantly use it so it's etched into the brain "OK, Grippledizing means Place at a spot" - if it's just a one off thing there is no need for a "cute" name for it. This is similar to how some science fiction loves just inventing words for things that already have perfectly cromulent terms.
