Ruination is almost halfway to their goal on Kickstarter. They’ve posted up an intro to the rules in order to help them make up that last 50%.
From the update:
The Ruination Kickstarter site has been updated by the addition of an introduction to the Ruination rules. This will give players a quick look at how the game works and a short sample of play. The intro is a PDF and can be downloaded for free from the KS page.
