12/20. A collection of 7 adventures from TSR's Adventurers Guild program,this book is unusual in that it contains scenarios for a number of different game systems. I've read rather than played through these.
Vale of the Dragon Oracle. AD&D 2nd ed Forgotten Realms. 4-6 characters of 5-7th level. Plays to the strengths of the Forgotten Realms setting, its background with the PC's stumbling into a fight between the Zhentarim & the Cult of the Dragon in a newly established Cult base. Includes a nice tie-in to Spellfire with reference to the cult attempting to resurrect the Dracolich Aghaztamn from that novel. Uses material from Cult of the DragonPowers & Pantheons & The Complete Book of Necromancers
Return of the Pick-axe. AD&D 2nd ed Greyhawk 4-6 characters of 7-9th level. The characters are hired by a dwarven clan to recover an artifact from a mine over-run by undead, only to discover that the artifact is not what they expected. Nice twist.
Blood Feud. AD&D 2nd ed 4-6 characters of 7-8th level. Characters are hired by a githzerai raiding party to help hunt down the survivors of of their attack on an mind flayer city. Uses material from The Illithiad Does a nice job of showing the different mind flayer creeds & an interesting idea to have the players working with a race they could easily encounter as foes.
The Manxome Foe. AD&D 2nd ed Planescape 4-6 characters of 8-12th level. Linked to Tales from the Infinite Staircase adventure anthology & set on the plane of Bytopia so Planes of Conflict (AD&D/Planescape) BOX SET would also be useful A Deva (angel) sends the characters on a quest with a Tanar'ri (devil) it has captured to slay a monster. It hopes that performing this good deed will re-ignite a spark of good within the Tanar'ri and allow it to choose to abandon its evil existance.
The Heart's Final Beat. AD&D 2nd ed Ravenloft 4-6 characters of 6-8th level. Uses material from Champions of the Mists: Ravenloft Accessory:. A messenger bearing knowledge of how to destroy an evil artifact has gone missing. The characters must re-trace his steps and rescue him or recover the letter he carried. Does a nice job of introducing some of the secret organisations both good and evil of the Ravenloft setting.
Leviathan's Deep. Saga game rules. Uses the Dragonlance Fifth Age: SAGA System BOX SET setting. The characters are on the fishing vessel High Stakesas it travels to the Leviathans Deep region of the sea to seek phosphorescent kelp from the Dimernesti elves to allow the people of Port Balifor to light their newly excavated city. Port Balifor and the surroundings are detailed in Heroes of Hope
Folds in the Tapestry. Alternity: Science Fiction Adventure Game adventure for 4-6 characters. Requires the use of Alternity: Player's Handbook. Collonists on the planet New Mojave are under attack from a newly encountered race known as the Rugs. Characters must establish contact with the Rugs and engage in a game of capture the flag with them for ownership of the planet.
Overall a nice collection of adventures that does its job of showcasing additional TSR rule supplements and settings.
I haven't actually played any of these, but they read well. Each of the seven self-contained "Adventurer's Guild" scenarios is designed for 4-6 mid-level characters, and takes place in a different TSR/WoTC game setting, as follows:
