Full Disclosure: I got this as a "pay as much as you want" and spent $1USD. Secondly, I don't know the system all that well, I own the Fate Accelerated booklet, and my personal experience was a disastrous Dresden Files demo (due to two players backseat DM'ing, and the system being harder than advertised) and will be reviewing this as a stand alone product.
First off, I am a little disappointed because I was under the impression that this book would have a full setting in it. Instead we get seeds and suggestions, maybe a hint or two of a real setting. That being said, however, what it does have is a series of very useful character creation tables, and ideas for a Do-It-Yourself world based on various 80's and 90's power science-fantasy cartoons and movies. What you get is really well done, but I personally want more. Perhaps more Masters detailed, what the world is like, some kingdoms both good and evil and maybe more super-tech/magic, it doesn't matter what, just more than what this booklet offered.
Still, you're allowed to spend as much as you want for it, which means you decide how much value it has. Personally, I found it worth the U.S. Dollar I spent.
I wouldn't complain if this turns out to be a primer for a fully fleshed out setting down the line, however. That would definitely get more of my money.
