Another OotS Kickstarter supporter and yes - totally worth it. Got the three books plus a couple of coloring books, magnet, etc, and various e-rewards.
I’ve funded three others - the one that I’ve gotten the reward for was a bit of a disappointment, and the other two I’m still waiting on. I got an email this morning for one of them telling me that my reward was now on a shipping vessel from China and that I could literally track its progress online. Neat!
