Top marks for the concepts in this book. I particularly like the way that the books are organised by the foibles and intentions of their authors, more than by the game rules.
The game mechanics are not so good. In places they are confused, or perhaps just confusing, as when the text refers to fighters being unable to gain ranks in Open Lock. More broadly they are just too strong, especially for non-magical items costed in the hundreds of gold pieces. Some of these problems can be fixed by fairly obvious adjustments, others (such as the two books of monster lore) would need me to devise entirely new mechanics before I'd be prepared to use them in a game.
Just to be clear, I've rated on my enjoyment and inspiration from the work, which both are considerable (on flavour text, if you prefer). As a rules document I found it deeply flawed.<br><br><b>QUALITY</b>: Acceptable<br><br><b>VALUE</b>: Satisfied<br>
