That's right, a real geniune hard cover that can be opened and closed, and has drawings of women. "MACHO WOMEN WITH GUNS" is boldly displayed on the spine, where you can read it when the book is shelved with all your other gaming books.
As you can see, you have a lot more pages in the hardcover than were in the original photocopy. It's up to date D20 Modern, complete with the gaming license, which means you can use all your D20 stuff with this setting, and use the setting's stuff in your other D20 games.
The book is quite filled with good information. The occupations and advanced classes are entertaining, the feats and heinous drawbacks are entertaining to read. The different regions of the world are well detailed.
Also, the storyline is updated to include mention of the Catkins diet. It is definitely worth the money, and brings a lot to the table. Certainly, a lot less thought went into this product than goes into a typical Privateer Press product for Iron Kingdoms (where they spend a year working out the econo-social dynamics of the invasion of Llyel on the price of coal in Khador before they release the World Guide).
I don't know what the original game was like, but the D20 version certainly benefits from all the tactical goodness of the D20 system. I highly recommend picking it up.
I also hope Mongoose someday publishes more material on this game, especially adventures. hint hint.
