The Good: Lots of content, Excellent descriptions, Quality and Quantity are both very good, nice detailed new creatures, info on different sorts of forests. Good value.
The Bad: Illustrations are just OK, It's just the descriptions.
This is a really nice product that adds little details for the type of terrain. It's hard to imagine the amount of detail contained. You could run an entire campaign in the woodlands just dropping a few details here and there with this product. The monsters are well described and interesting. The language journalistic rather than evocative in most cases. The illustrations are average.
