For me it's strongly fun. But there are ways to reduce the fun and make it work.
Having the reading be overly reference-y, with different parts needed to understand the whole not presented up front but instead with some in later parts so I am missing context to make sense of the first part.
Having it be written in an overly dry, technical writing sort of way. An RPG I enjoyed reading was 13th Age, with it's regular sidebars from the two authors delving into why they made such and such a rule, or ways to tweak it, or even where they disagreed and why.
Having it present the "same old". If the game retreads things I already know, or worse stuff very close but nitpickingly different than what I know, I dislike it. The first is boring, the second is boring but necessary - a chore. A friend was going to run SW5e (Star Wars 5e), and some of it was fun to read, but the tech section which was basically 5e spells but with tweaks was a labor to get through. I needed to see what whas there, see what changed so it required a close reading, and also sort of mentally categorize what wasn't there that I expected, which since they updated names for the flavor was not easy.
A subcategory of that is reading some old RPGs are cringeworthy, as I see ideas that I know but have been supplanted by time and advances in the state of the art.
But baring that, getting a new RPG and going through and seeing all the new ways of doing things and the elegant mechanics and resolution systems (because who publishes in this mature day and age with an outdated system) is great fun. I've got the new Cortex Prime book from the KS sitting a few feet from me and I'm looking for a good uninterrupted block of time to dive in.
EDIT: Most people were talking about learning from reading the book, so that's how I replied. But really my learning continues into play. (And I have done simulated play with systems just to grasp it better.) And that's where the fun can really come home to roost. When I see the piees and they come together in my head can be a real joy. When I start to build up system mastery and comb through again with a deeper understanding of how it fits together - that's a great feel.
