The Puzzle of Life will come with two companion booklets: the Player's Guide, and the Yellowstone Storybook. I've just finished early drafts of both documents, and both are in need of new eyes and new readers. [gallery columns="2" ids="879,878"] To that end, I've posted the files here: trophic cascades. The Yellowstone Storybook tells the story of a rather famous trophic cascade in Yellowstone, and it does this by using changing arrangements of Puzzle pieces to show how the Yellowstone ecosystem has changed over time. I hope this story will inspire players to make their own pieces, tell their own stories (both fact and fiction), and to learn more about the natural world. But the punchline of all this remains: Feedback! Please. Both these guides are obviously incomplete, but I've stared at them for long enough that I can no longer see the forest for the trees. The more different people who take a look, and share their thoughts, the better the end result will be. You can reach me via email at: tim.handley AT mindfulmammoth.com.
