I ordered it. It doesn't seem like a dramatic difference from the main game but enough to get me to pull the trigger. I like legacy games so this was my main reason to get it. My wife and I play Sagrada daily (mostly on mobile) and thought this would be a good addition to our collection.

I love Sagrada and I like the idea of Sagrada coloring books but it's still way too expensive for me. The retail pre-orders are closer to $50 vs the almost $100 (with shipping) KS pledges but that still seems a lot for what I've seen so far. I hope somebody does a more spoilerful review at some point because I am not ready to make the jump blindly.
