Could you see yourself using any of this book's elements in your own roleplaying? I can definitely see myself using the Mayan pantheon as revealed here, and even the conceit of having to travel from place to place to retrieve parts of Hum-Kamé's body. The set pieces work for me as encounters, too. I became very aware of this in the encounter with the Uay Chivo. I could see a party coming up against him, and it just clicked.
What do you think?
