Even though it's been said by multiple reviewers already I have to start off by saying this is a gorgeous book with really well done art and cartography throughout. Even if you don't get to play through as much of the material as you would like, both visually and as a book just to read Uncaged Vol. 1 is extremely well executed and a tremendous bargain for the price.
On my first read through I was primarily focussed on the Tier 1 content as that is my current group's play level and even though that represents a lot of content from multiple writers and artists I found that overall the adventures had a great "feel" by being simultaneous somewhat familiar while mixing in fresh takes and twists to remove predicability.
I wholeheartedly recommend this book. It is objectively well written, designed and illustrated, and I think every DM could find multiple scenarios their groups would enjoy.
Can't wait for Volume 2!
