I understand the reasoning as to why the rules are written the way they are (accessibility to readers who are not yet gamers). However, I struggle with distilling out the essence. For instance, the -- very simple! -- rules for a Challenge spread over 13 (!) pages. There is no summary anywhere; a handwritten one I created is half a page. (not much meat there...). I do like the running examples, but they seem to be used to clarify rather than illustrate rules in multiple instances (see several rule discussions). This is bad, imho. The core rules should be stated clearly somewhere.
This is, in particular, an issue when looking up rules (as opposed to initially learning them). No way can I skim 13 pages in the middle of a session, looking for the clause containing the bit of information I need.
Note that this is certainly an issue of personal preference. I am definitely a techy/sciencey guy, so I generally prefer tables over text for clarity; others may have other preferences. I do think, however, that the lack of succinct and unambiguous reference material is a huge oversight, especially because (in my experience) Sci-Fi/Fantasy fans and roleplay gamers are techy with relevant probability.
Rewriting the affected chapters is certainly not realistic at this point. Please consider adding some pages to the appendix that summarize the core rules in a clear way (maybe even flow charts?).
A related issue is one that is, in my opinion, responsible for much of the rule bloat I have perceived. While explaining the basic rules, lots of Narrator/GM advice is given. For instance, "Describing Outcome" takes up over 4 pages before the basic concept of complications can be introduced. While I treasure such advice, it should be better separated from the meat. You do have separated book for special Narrator information already, maybe move the content there? Else such hints should maybe be moved to special boxes more rigorously.
