Catacombs Solo Quest

Remember these? I read them late into the night, they were some of the best flights of fancy I had as a preteen. I mean, Faerie Mound of Dragonkind! Swoon! And Gnomes-100, Dragons-0? Hilarious and full of magical blueprints for gnome launchers and the like. Amazing.

These large-format gamebooks were one of TSR's last forays into the form. Each book contains about 150 pages and numerous illustrations. Three of the books are set in various Advanced Dungeons & Dragons settings, while two (including the unpublished fifth volume) are inspired by the Top Secret/S.I. role-playing game. Rules vary from book to book, but each volume includes some extra items used during play (multiple character bookmarks for the AD&D adventures and a flap full of "clues" like computer printouts and maps for the Top Secret book) and a combat system. The AD&D adventures use twelve-sided dice while the Top Secret one uses ten-sided ones; in either case, dice rolls are printed on the bottoms of the pages so that players without dice may flip through the book at random to generate numbers.
