Just had to say I'm incredibly impressed with this game. Dino Island is now in my PbtA, one-shot quiver alongside Zombie World & Bluebeard's Bride. The structures and tools you provide to tell a satisfying story are top notch. Looking forward to running this a couple times over the holiday season.
I particularly love the "tell a story" mechanic. Such a brilliant way to introduce backstory / character development into the natural flow of the game. Already thinking about how I can hack this into other games.
Also, I'm recommending this game to players in my group who want to try out GM/MCing (Dino Mastering) for the first time. I think the game does such a good job setting the MC up for success.
