Rules and ideas to turn your Imperial Age game into a Steampunk or Gearpunk game. This book goes beyond what is presented in Gentleman Scientist and presents a new campaign model.
More so than the other books in the Imperial Age line this one has more d20 information. There is also less "history" than the other books.
Despite all of that, this is a good supplement to add all sorts of things to your game. If you are a fan of Steampunk/Gearpunk and your current Victorian Game of choice does not support it, then this is a good choice. If it does then this is a great source for more ideas.
All the Imperial Age books are all well written and features art from the age, either public domain art and paintings as well as some original art. In all cases the art is very evocative of the time and very well done.
The books are all easy to read, with clean layout and font sizes. They can be printed with ease without killing your printer cartridge.
