Going through the book, I found myself feeling the same level of excitement I felt as a kid with AD&D and Gamma World material.
The system looks really good (you need the core book, this is a supplement). It feels like a combination of the best of Fate Core and Savage Worlds. I've been looking for a game that is a bit crunchier and less open ended than Fate Core. Savage Worlds was looking good to me, but there was something about it that just didn't fit for me personally.
Ubiquity looks like it may be my next favorite system.
This supplement contains a great deal of wonderful content and fantastic art.
The world contains an enormous amount of personality and spirit which is brought to life here. So much content is borrowed from so many sources, yet the book manages to create a sense of coherency. It comes across as being its own thing rather than some Frankenstein's monster, which is a danger for this kind of synthetic material. It is dynamic instead of chaotic.
That is a great accomplishment, I think.
Judge for yourself by taking a look at the sample characters from Exile's website.
