This is a great refresh of the original product. It looks great, and read well. A lot of errata and other updates are slipstreamed into the text. This is the first product of a huge update and expansion of the Amethyst line, including support for Dungeons and Dragons 5th edition (when 3pp is fully defined and live) along with Fate Core, 13th Age and Savage Worlds in addition to Dungeons and Dragons 4th edition and Pathfinder.
The author and team did a great job with the original product and this refresh ups the bar for independent game producers.
If you want a science fantasy setting, this is one of the best ones on the market. It is versatile enough to accommodate most playing styles easily.
[5 of 5 Stars!]
