A truly disturbing look at the End of Days, and the downfall of man, this book does quite well in building a realm of horror, war, and desperation, even despite its many - MANY - typographical and editorial flaws.
I'm sure these design flaws and layout issues have been fixed in further editions, but I gave the book the rating I did because it's almost impossible to use a book that tells you to go to "page 00" when you're trying to look something up.
Additionally, some of the font choices and layout styles could have stood for some polish and dazzle from a professional, even though for the majority of the time, the book isn't difficult to follow, read, and enjoy, with one big exception. Right smack in the middle of the book is a large section on the game's history, and it's done in a type of font that I found impossible to follow after a few lines. Choosing a different typeface would have made this section easier to deal with.
Still, when putting out an RPG, I'm sure that there are timetables to be met, and this can cause such issues to arise.
As far as the writing goes, well, throughout much of the book, it is average-to-better-than-middling throughout, with some exceptional areas scattered throughout. First, the cosmology is an interesting take on Genesis and the creation of the universe, thought it could do with some spit-and-polish in areas. Part of this problem might be the fact that there is so much that the book is trying to deal with: Demons, Angels, Fae, Elementals, the unnameable Cthulhu-esque Evil that is trying to destroy mankind, the Old Gods, and so much more.
