Capsule Review by Eric Brochu on 10/05/97 for RPG.net
"Enough with the gushing-- this group of scenarios starts out in typical Cthulhu fashion being small, with greater horrors being unleashed along the way. The central "villains" within the book are ghouls, and a certain deadly cult. Within the course of the book certain mysteries will be solved, war will begin, and investigators will travel to French Guiana, the Dreamlands, and back again." (Capsule Review by Scott Shafer on 03/03/98 for RPG.net)
"Finally, no review of Realm of Shadows would be complete without stating that it is illustrated by the one and only Blair Reynolds. His art is extremely disturbing. This makes it ideal for Realm of Shadows, a product which is intended for mature gamers." (Capsule Review by Lisa Padol on 11/14/97 for RPG.net)
"It's in the locations, though, that The Realm of Shadows really shines. French Guiana (where the notorious French prison Devil's Island is located) is a terrific setting -- equal parts prison colony, frontier town, and _extremely_ inhospitable wilderness -- and the book makes the most of it. The Dreamlands locations are appropriately mysterious, exotic and eerie, and the Massachusetts locations have plenty of local color and interesting NPCs.
"The best thing about The Realm of Shadows, though, is just how well it is written and designed as a game accessory -- I really hope other game writers read it and learn from it."
