A bit expensive for just 32 pages...if you want your books to be jam packed with writing. If you go with the author's "bottom up" method of universe creation it won't be such a problem. And if you like evocative art to get your juices flowing then this is right up your alley.
If you were to cross Guardians of the Galaxy with the Heavy Metal movie and toss in a dash of MST3K you are begining to get the idea of what this setting can be. However, since this is a Player driven creation you could really use whatever comparisons you want.
This would be a great framework for any group that wants to explore/create their setting as they go, because it has enough info to get your creative juices flowing without putting you in a strait-jacket.
There is a Fate Core add on that you can purchase separately, because this is a system agnostic product.
I didn't give it 5 stars because I wanted more. However the concept is intriguing and well executed.
