WHAT WORKS: I don't really like Power Points, so an alternate magic system is always welcome. I like the wide range of material covered in the timeline, from the beginning of magical crime through the end of World War I. The new Edges (mostly aimed at dogfighting) feel particularly appropriate, given the setting.
WHAT DOESN'T WORK: Setting-wise, it feels almost like TOO much has been crammed into one book...but I could also see how one could prefer that to a more limited book. Enterprising GMs can certainly expand from the material given, and if demand is there, Battlefield Press can always expand the setting with supplements. Minor quibble: A lot of earlier Savage Settings had the problem of multiple shared elements, namely zombies and Atlantis, so linking the events of Kaiser's Gate to the Tunguska event immediately took me back to Necessary Evil, which does the same (albeit with a completely different result).
CONCLUSION: First off, it's nice to see something focused on World War I instead of World War II. Second of all, they showed a lot of restraint with the new material added, especially Edges, focusing on expanding aerial dogfighting. The races are included with a caveat of "Humans are the default, the rest must be approved by the GM", and I vastly prefer options to turn on and off over omission in just about every case. There are some d20isms still present, including the racial selection, some of the new spells and the magic item selection. I always like a good bestiary, but a lot of what you need for this is already going to be in Savage Worlds. Lastly, in an odd note, it refers you to the Explorer's Edition over the Deluxe Edition. Very good work here and a great time to jump on, with the Kickstarter still in effect, because of all the bonus material that has already been unlocked.
