I've grown to realize how amazing RPG books are that give you all the tools to create an entire adventure. Beyond Corny Gron is one of those books, and its flavor is second to none. There are tools for everything you need, including for creating mountain regions and caves, and a truly stunning bestiary that keeps going and going, and much more. And the art is the first thing that attracted me, back in regard to the original Corny Gron book (I have one of the prints hanging on my wall), and this book just amps that up by a thousand. Amazing stuff.
