This is an amazing product!!! While best suited for an FR Campaign, any DM could benefit from the information here, especially from the section on each god's dogma and the Specialty Priests (after all, Tempus is a pretty typical war god and that Talos kit works well for priest of a god like Zeus). The Demihuman Deities book is perhaps even more useful as these gods, like Moradin and Corellon, are involved in many D&D worlds. GET THE BOOK!!! No matter what the bad reviews may say, this IS NOT reprinted stuff... the SP kits in FR Adventures were terrible and as far as sitting down and doing all this yourself, GOOD LUCK! This is the best roleplaying product in the TSR line.
