I won't lie. I LOVE Monster books. They are to this day one of my favorite things to buy for any game. The Amazing Adventures Manual of Monsters manages to give me monsters I have seen before, but with a whole new take. I mean a mummy is a mummy right? Well...your old monster book won't tell you how it reacts when you fire your .38 into it. But beyond that this book also has a lot of new monsters. Enough to make it worth while in my opinion. Also as an added bonus feature is an appendix of monsters from different countries. So fight that Kelpie on it's native soil. Or tangle with the machinations of the Greys. If you play AA then you need this book.
