19 Adventures in the Running for 10 Greatest Adventures Since 1985

For my list of the 10 greatest adventures since 1985, nominations, reviews, and reputation led me to consider many more excellent adventures than fit a list of 10. Today’s post reveals the adventures that fell short of my 10 greatest, but merited consideration.


Treasure Hunt (1987) is a first-edition Advanced Dungeons & Dragons adventure by Aaron Allston.

Raw characters with no class levels wash up on the lost island of the pirate Sea King. They advance to first level and beyond.

“As a first adventure for initiates, this can’t be beaten. For old hands who may be tiring of AD&D, it will be a welcome change.” – Carl Sargent in White Dwarf issue 93.


King’s Festival and Queen’s Harvest (1989) are basic Dungeons & Dragons adventures by Carl Sargent.

A pair of adventures that introduces new players to D&D with a variety of linked missions.

“Absolutely the best introductory adventures in print for D&D-game-style fantasy role-playing games (FRPGs). Presented simply and clearly enough for young folks, these adventures are also challenging and entertaining enough for experienced gamers.” – Ken Rolston in Dragon 171.


Ruins of Undermountain (1991) is a second-edition Advanced Dungeons & Dragons adventure by Ed Greenwood.

The first three levels of the mega-dungeon under the city of Waterdeep presents its content with different levels of detail: Some rooms have complete descriptions, while others have terse notes. Most sections remain empty, a canvas for the dungeon master’s creation.

Rated 17th greatest adventure by Dungeon magazine.

Ruins of Undermountain was as much stuff from Ed Greenwood’s original gaming sessions as he could fit into a box. I give Ruins of Undermountain an A+. It will make you a better DM regardless of your skill level. This is a glimpse behind Ed Greenwood’s screen, giving the reader a chance to study his methods, which are very sound.” – Advanced Gaming and Theory


Vecna Lives! (1991) is a second-edition Advanced Dungeons & Dragons adventure by David “Zeb” Cook set in Greyhawk for characters of level 12-15.

After the Circle of Eight, Greyhawk’s legendary adventurers, die trying to stop Vecna’s return, their successors hunt the villain in a chase the across the world of Greyhawk.

Vecna Lives! is one of my favorite adventures from second-edition Advanced Dungeons & Dragons and I’m ecstatic that it’s been made available on dmsguild.com. Even if you never play the adventure, you should go out of your way to read/download/borrow it just to see what an incredible example of storytelling and adventure writing it is.” – Die Hard Game Fan


Night of the Walking Dead (1992) is a second-edition Advanced Dungeons & Dragons Ravenloft adventure by Bill Slavicsek for characters of level 1-3.

Characters investigate a series of murders an disappearances in a village plagued by walking dead.

“The actual adventure is one of the better blends of plotted adventures and old-school adventuring found in the ’90s. Though, there’s a deep, underlying story, it’s not a railroad. Instead, players must investigate and interact with NPCs to figure out what’s happening. Some events act as set encounters, but there’s also a big dungeon (cemetery) to crawl through at adventure’s end. The result maintains player agency while still telling a real story.” – The Fraternity of Shadows


Merchant House of Amketch (1993) is a second-edition Advanced Dungeons & Dragons Dark Sun adventure by Richard Baker for characters level 4-7.

In an event-driven adventure, characters work to end a trade in beetles with a bite that neutralizes psionic power. The quest pits the party against the most powerful merchant house in Tyr.

“This adventure has everything for me: intrigue and adventure coupled with the potential to save the world from a great threat that has just been exposed. So it’s 5 out of 5 stars.” – Warpstone Flux


City of Skulls (1993) is a second-edition Advanced Dungeons & Dragons adventure by Carl Sargent for characters of level 9-12.

Players infiltrate the demi-god Iuz’s nightmare capital to free a military commander needed to defend the Shield Lands.

Rated 26th greatest adventure by Dungeon magazine.

“Periods of stealth and quiet punctuated by short bursts of terrifying combat.” – Retro Gaming Magazine


Night Below: An Underdark Campaign (1995) is a second-edition Advanced Dungeons & Dragons adventure by Carl Sargent that takes characters from 1st level to as high as 14th level.

Billed as the “ultimate dungeon adventure,” this campaign goes from a ruins crawl, to a mine crawl, to a long journey through the Underdark.

“Night Below won’t be to some peoples’ taste, but the vast majority will absolutely adore it. Quite simply, it’s one hell of an adventure.” – Cliff Ramshaw in Arcane magazine.


Return to the Tomb of Horrors (1998)  by Bruce Cordell.

Years after adventurers gutted the original Tomb of Horrors, a dark community has built a city of necromantic evil on the tomb’s site. Even the inhabitants of this fell city have no idea of the true evil that waits beneath them.

Rated 10th greatest adventure by Dungeon magazine.

“The new material is really excellent. Return is a whole mini-campaign, not some rehash of previous work … It offers more by far than the old Tomb of Horrors, and it is more deadly too.” – Gary Gygax


Dawn of the Overmind (1998) is a second-edition Advanced Dungeons & Dragons adventure by Bruce Cordell for characters of level 8-10.

To stop a resurgent mind flayer empire, character visit a world of ancient ruins in search of an artifact of Illithid manufacture. This adventure brings a taste of Spelljammer and sword and planet adventure to conventional D&D.

“This is the third part of the Mind Flayer Trilogy, which was pretty much awesome from start to finish. One of the best D&D adventures of all time.” – Power Score


Die Vecna Die! (2000) is a second edition Advanced Dungeons & Dragons Adventure for characters of level 10-13 by Bruce R. Cordell & Steve Miller.

Die Vecna Die! takes the heroes from the Greyhawk campaign to the demiplane of Ravenloft and then to the Planescape city of Sigil in a quest to claim the Hand and Eye of Vecna—the key to stopping the evil demigod Iuz.

Die Vecna Die! pulls out all the stops, and the result is a massive but tightly constructed adventure with a truly apocalyptic feel. I’m surprised I’m recommending Die Vecna Die! as strongly as I am, but it’s just that good. It’s a great high-level adventure for any campaign.” – Fearful Impressions


Forge of Fury (2000) is a third-edition Dungeons & Dragons adventure for levels 3-5 by Richard Baker.

In a dungeon that captures the flavor of some of D&D’s original, classic adventures, characters battle though five levels of a dwarven stronghold overrun by evil.

Rated 12th greatest adventure by Dungeon magazine.

“I’ve always been impressed with the adventure; for my money it’s one of Wizards of the Coast’s best 3rd Edition era modules. As a basic, flavoursome dungeon crawl I think Forge of Fury is particularly well executed.” – Creighton Broadhurst


Return to the Temple of Elemental Evil (2001) is a third-edition Dungeons & Dragons by Monte Cook designed to take 4th-level characters as high as level 14.

Power rises again in the Temple of Elemental Evil. “Characters battle the power of darkness in Hommlet and beyond, forging their way through hundreds of encounters before reaching the fiery finale.”

Rated 8th greatest adventure by Dungeon magazine.

“Go out and buy the Return to the Temple of Elemental Evil. You will not regret it, and it will become a valuable part of your D&D library. It is one of the best adventure modules ever written.” – Talon on ENWorld


City of the Spider Queen (2002) is a 3.5 edition Dungeons & Dragons adventure by James Wyatt designed to take 10th-level characters up to level 18.

“Daggerdale is reeling from a sudden series of murderous drow raids. As a grave threat to the entire surface world develops in the war-torn dark elf city of Maerimydra, intrepid heroes must discover its source and destroy it, if they can.”

Rated 24th greatest adventure by Dungeon magazine.

City of the Spider Queen is an excellent addition to anyone’s Forgotten Realms campaign or with modifications, any Dungeons and Dragons third-edition game.” – Mania.com


Reavers of the Harkenwold (2010) is a fourth-edition Dungeons & Dragons adventure for characters of level 2-4 by Richard Baker.

In an adventure patterned after Red Hand of Doom, the characters join the resistance and take missions to thwart the army of evil that invaded the Duchy of Harkenwold.

“Definitely one of the best 4E adventures. – Will Doyle.

“I would love to see a 5E update of Reavers of Harkenwold.” – Chris Perkins


The Slaying Stone (2010) is a fourth-edition Dungeons & Dragons adventure for 1st-level characters by Logan Bonner.

Years after goblins overran and occupied a town once settled by humans, the characters enter seeking a lost Slaying Stone, the last of the magic stones created to protect the settlement.

“This is an adventure you won’t want to miss: Not only is it fun and non-linear, but it shows a DM how to better design her own adventures, and that’s something worth reading for any DM, no matter how experienced.” – Kevin Kulp


Dreams of the Red Wizards: Dead in Thay (2014) is a fifth-edition Dungeons & Dragons adventure for characters level 6-8 by Scott Fitzgerald Gray.

Teams of adventurers cooperate to explore a massive dungeon in search of the keys to a phylactery vault held by the evil Red Wizards of Thay.

“A ton of fun. Things get more and more hectic as the alert level of the Doomvault rises. It’s got good pacing, a narrative to it, and some fairly challenging encounters.” – Bell of Lost Souls


Cloud Giant’s Bargain (2016) is a fifth-edition Dungeons & Dragons adventure for level 6 characters by Teos Abadia.

Led by a talking skull, Acquisitions Incorporated interns enter a cloud castle floating over Neverwinter to determine what threats it holds. This superb adventure combines combat, exploration, and interaction with interesting choices into a single session of play. Plus it adds a touch of humor and an unforgettable guide.

Megadungeons in print and on the web

Perhaps few people play megadungeons, but my look at the era when megadungeons ruled Dungeons & Dragons and why few people play them anymore revealed great interest in vast underworlds. So in this post, I present the megadungeons in print or on the web.

To qualify for my mega-list, a dungeon must meet three qualifications. It must be…

  • in print or on the web in a form close to playable.
  • suitable for the focus of an entire campaign from low to high level.
  • too big to clear of traps and monsters, even as the focus of a campaign.

Most of these products attempt to recapture or update the play style of the original campaigns that launched D&D, so many use rules that emulate either original D&D or AD&D. If you prefer advantage, concentration, and armor classes that go up, you can play these dungeons with fifth edition. Just use the monster stats in your new manual and make up any difficulty classes as you go.

Rational: Ambient magic? Insane wizards? The mysteries of Dragon’s Delve remain locked from my gaze.

Why Dungeons & Dragons players stopped exploring megadungeons

In my last post I wrote about how Dungeons & Dragons creators Dave Arneson and Gary Gygax built their campaigns around huge dungeons that grew and changed. These megadungeons enabled Dave and Gary to run campaigns for dozens of players. On any day, they could host games for whoever happened to show up for a session.

Even though the megadungeons under Greyhawk and Blackmoor became the foundation of Dungeons & Dragons, such dungeons rarely see play anymore. Why not?

Players never saw any examples. Originally, Gary thought that players would never pay for published dungeons. After all, players could easily make up their own. Despite this belief, TSR distributed the first published dungeon, Palace of the Vampire Queen. Strong sales proved Gary wrong, and so he set to publish his own dungeons.

But Gary’s megadungeon under Greyhawk Castle seemed impossible to capture in writing. As adventurers explored and plundered, the dungeon changed constantly. New monsters wandered in to take empty rooms. Whenever the players’ attention turned, the layouts of old levels subtly changed. Entire new levels appeared. Most of the content lay in one-line descriptions, or worse, locked in the heads of Gary Gygax and co-dungeon master Rob Kuntz. Decades later, Gary wrote, “If we handed over the binders containing the maps and the notes, I don’t think even the ablest of DMs would feel empowered to direct adventures using the materials.”

So rather than attempting to capture Greyhawk Castle, Gary opted to publish adventures that he had created for D&D tournaments at conventions. For instance, the official D&D tournament at Origins ’78 ran the G1-3 adventures. The choice to publish such adventures changed the development of the game. D&D players everywhere saw Gary’s published adventures as a model. Instead of patterning their games after a megadungeon like the one Gary played at home, players imitated adventures created for a few hours of competition.

The Ruins of UndermountainIn 1991, TSR finally published The Ruins of Undermountain, its first megadungeon in print. Undermountain appeared in a box with maps and with booklets that sketched out encounter areas. This outline mirrored the terse descriptions and evolving notes that Gary Gygax used for Greyhawk Castle, but the sketch failed to satisfy DMs accustomed to publications ready for play.

Perhaps locking a megadungeon in a box kills it. Printed pages cannot capture the dynamic essence of those original levels.

The ecology and rational of megadungeons seemed ridiculous. From they start, players struggled with the logic of megadungeons. Where did all those monsters get their food or leave their waste? Where did the creatures and treasure come from? Every dungeon master invented an insane wizard as an architect for their game’s underground sprawl until the notion became trite.

In the little, brown books, Gary suggested dungeons with layouts that always changed and grew to “maintain freshness,” but that made the megadungeon even more implausible.

Then Gary published adventures that featured a logic sometimes called Gygaxian naturalism. Monsters had lives of their own that involved feasting, scheming, sleeping, and everything but waiting for heroes to come kill them. Rather than wandering monsters living in defiance of reason, we saw giants and drow in their steadings and vaults. For many players, the giant- and drow-series adventures set an example that killed the megadungeon.

Soon, any DM peddling a megadungeon had some explaining to do. For instance, The Ruins of Undermountain kept to the insane wizard trope, then added magic that continuously gated in fresh monsters from across the Realms, and deep entrances that allowed creatures from the Underdark to well up.

Play styles expanded. Sometime in the middle of the 70s, for the first time ever, a party of adventurers visiting the inn met a hooded stranger with a job that needed doing. D&D expanded beyond a series of dungeon expeditions aimed at claiming treasure. Players began to favor games that mixed action with story. Kicking in endless doors to fight and loot turned from fresh and thrilling to a tiresome slog. Today, avid D&D players can claim that they don’t like dungeons or can say that their best games lack any combat. Even those of us who like dungeon crawls want to see some daylight and a plot.

Computers do megadungeons better. In 1979, computer games like Akalabeth and Temple of Apshai took gamers into megadungeons and started an electronic-gaming genre. Dungeon crawls limit players’ options, so they offer an easy premise for a computer game. See “How the dungeon crawl’s advantages propelled Dungeons & Dragons to success.” With a computer DM, players can explore anytime. Digital dungeons offer faster play and better graphics. For players who just want to visit a sprawling underworld to kill monsters and take their stuff, electronic games probably offer a better experience.

Can a megadungeon work today?

A clever design can avoid the problems that pushed megadungeons out of play.

A story-centered game can take PCs into a megadungeon to accomplish more than looting. For instance, when Monte Cook created his superdungeon The Banewarrens, he paired it with overarching plot. Players don’t raid the Banewarrens just to loot. Instead, the story leads to objectives that require missions into the place.

Many megadungeons avoid monotony by introducing levels or zones centered on unique themes such as crypts, flooded sections, or fungus gardens. Even the levels under Castle Greyhawk followed themes that grew more exotic at deeper levels.

A megadungeon design can add intrigue by borrowing a page from The Keep on the Borderlands and adding factions of monsters. Players can join a side or play one against another. Factions under attack will bring reinforcements, creating more interesting battles, and giving players a reason for caution. The stories “Red Nails” by Robert E. Howard and “The Lords of Quarmall” by Fritz Leiber helped inspire the concept of dungeon exploring. Both yarns centered on feuds and intrigue.

A world of fantasy offers plenty of possible justifications for the strange things in the underworld. More on that in my next post.

A megadungeon (and a live DM) can create player agency and tests of ingenuity that no computer can match.

Although good design can yield a megadungeon that proves fun to play, ordinary dungeons can being the same advantages. Today’s gamers tend to create megadungeons to foster nostalgia or to enable episodic play.
