Extremely informative, and organized for maximum usability. This document has everything from tables of radiation exposure, to world tropes, to resources and hazards of ring systems, and even a page on the visual size of a gas giant in the sky depending on its distance from your characters--something I've actually tried to work out with pencil and paper before, dredging up high school math from the depths of my mind.

This book is great value for money. So many ideas. So much information. I highly recommend this for anyone interested in a gas giant setting for their game or book, or anyone interested in gas giants. I look forward to more books from Dr Freeman.

If you really want to bring Gas Giants alive in your games (and not just as a place to refuel a ship) then this gives you lots of useful ideas. There's a bit of maths if you want to calculate things yourself, but it's not necessary to make use of the product. I liked the table of damage caused by running into micro-meteorites of different sizes and speeds. How may other products give you hard data on the amount of radiation you can take? Perhaps there's something valuable on a moon, but it's in the radiation belt. It's going to cook electronics and defeat your protective suit in 2 hours. How are your players going to get to it? There is some nice colour artwork, and some black and white art that I thought didn't really add to the product, but did break up pages of text. This is not a scenario, but it gives you a lot of ideas to help you make one yourself. Worth paying for.
