This book is great. It is one of the most detaield and comprehensive equipment books I've ever seen. It's useabel with D20 and Hackmaster games (and as such any oldschoolRPGs as well).
I'll mention just a few bits about this comprehensive book.
The discussion of the marketplace and the buying and seeling of goods, taxation, coinage and more is solid.
There are a lot of weapons with identical or virtually identical stats but they have decent write-ups that add some flavor to the game.
The clothing section is great and almost worththe price of purchase alone. There are rtuels about style if yuo want to bother but even better is the simpel fact that clothing pieces are described ..i didn't know what a braies or fillet was before I got this book.
there is a lot of crunch here, fillign lots of spots in many a campaign equipment list but also a lot of detail to help describe the world to the players in the manner of what various goods and gear look like.
