I don't know where to start. I got this product to get a basic bestiary with fantasy creatures I could use in a BRP fantasy game. First I found that this book is basically a reprint of the Runequest bestiary. None of the content are adapted for the new BRP book all creatures for example have their Moves listed as per the optional Strike Rank system for example.
The thing that bugs me the most are that a lot of the creatures are already available in the BRP book except for some classic icons like the Broo. And a lot of the creatures already listed have different stats forcing you to make the choice of which to use.
If the book had been reworked and updated to fall in line with the new BRP system the rating would have been a lot higher. A lot of the information is not much use and could be lifted out of the book completely without hurting the material. Instead it's still there taking up unnecessary space.
The book is not completely useless but you have to do some work for each creature you are gonna use and depending on what optional rules you are using. But if you are tight on money the money is better spend elsewhere.
