This review was published at RPG Now.
One needs to distinguish between the book content, and the actual product (in this case a PDF containing the scanned book). The book has parts that are still interesting today (strongholds!) – the reason I was disappointed, however, was that the PDF had so little usability. It is difficult to read on a screen, and practically impossible to print.

Returning to roleplaying after a long hiatus and wanting a cheap all-in-one reminder of what it was like back then, I decided to give the Cyclopedia a try. As it turns out, the book is what it promises to be: It has everything you need for old-school D&D.  Unfortunately, the book was scanned including page backgrounds and all. That’s why you get a grey shade on every page, and a 79MB PDF that’s practically impossible to print, and the few pages that you do print for offline reading will be hard to read if you try to cram two pages on one sheet of paper.
LIKED: All the old-school D&D stuff you need in one book
DISLIKED: Bad scanning makes this a huge file that is difficult to print and hard to read
RATING: ★ ★ [2 of 5 Stars!]
