The Sorcerers Crusade Companion is different when compared to other general RPG source books. This book does not contain a lot of game mechanics or new powers. It provideds all the necessary information to run a historically accurate Renaissance game. Everyday details such as fashion, food, behavior, and culture were all presented in just the right amount. The art of swordfighting, plants, famous Renaissance figures, and Umbrood were discussed in the core book but was elaborated here. Most importantly, the book discussed the other cultures of the world during the Renaissance and their beliefs. This opens a lot of doors for games involving explorers and diplotmats. This book is a must for the average gamer who knows little about the world during the Renaissance and would like to add some accurate historical flavor to their games that might otherwise end up like generic D&D adventures.
