Yes, Dimitri has it right. S&S Studios was a White Wolf publishing venture for the
d20 world when Wizards released the Open Gaming License (
OGL) and allowed other publishers to use Open Conntent in publishing game products. Before there was a Necromancer Games, or about the time it was launched, the Necromancer principals Bill Webb and Clark Peterson worked on the first S&SS monster book, Creature Collection, that was released in 2000 and beat Wizards to the punch. The official D&D 3.0 Monster Manual was released about six months after Creature Collection had been released.
Necromancer Games also had a book published by a small company called TableTop Adventures. The book, the Mother of All Treasure Tables, was distributed by Kenzer & Co. It's a neat book, in the vein of the other "Mother of" book that Necromancer did, the Mother of All Encounter Tables.
Here's the blurb about the Mother of All Treasure Tables (for any that are interested):
"The Mother of All Treasure Tables puts the "ah!" (or awe) back into your treasures!
"From the farthest corners of the earth, a vast array of treasure has been gathered. Never before has such a book been available, to provide with a simple roll of the dice a random selection of detailed descriptions -- treasures that include weapons and walking sticks, elaborate jewelry and wooden buttons, carved boxes with secret compartments, rare ivory and iron pots. There are statuettes, royal robes, belts, antique coins, and armor suitable for the greatest adventurers of legend. Each treasure has been carefully calculated based on standard values but there is nothing standard about these treasures!
"Here in a single volume are nearly 700 treasures to use individually or mix into an astronomical number of combinations, more carefully thought out and detailed than any before. Containing treasures suitable for the lowliest of pickpockets and brawlers or the most splendid of kings and queens, this book will augment your imagination and encourage your heroes to ever strive for more opportunities to obtain treasure. Creative flair and painstaking research together provide you with treasure that is as "real" as you can get in a world with dragons and wizards. This is the Mother of All Treasure Tables!"
