Not only does this book give some very unique interplanetary ideas, but is also very good to create earth based areas. That all comes with the fact, however, that this is an idea book like any gazatter.
This book runs through various inhospitable Terrain and the requirements to survive in them. With some clever alterations you can create very alien worlds with them. Those glaciers in real life that bleed red water because of heavy iron? Easily adapted to the Mars setting. Need a compelling volcano? The sun can help. Magic gas filling the area? Look to the gas giants.
Aside from the obvious and welcomed return of fantasy space this will be very much enjoyed by anyone who enjoys the most extreme fantasy setting. Again, this is a gazetteer so don't expect too much to be done for you, it just has the basics. Still the best example of a gazatter I've seen in ages.
