Gary Gygax is probably the best known name in Role Playing Games -- still, nearly 15 years after his death. Considered Dungeons & Dragons’ co-inventor and principal author of most of its early material, “Uncle Gary” was also a tireless promoter of his game and of role playing games as a whole. For the hobby’s ½ century Gygax’s name has been synonymous with it, he shouldn’t need an introduction, but it's still worth taking a close look at his adventure design legacy. Specifically how Gygax designed his dungeon adventures.
Gygax was author of many of the best early adventures for Dungeons & Dragons including: Steading of the Hill Giant Chief, Vault of the Drow, Village of Hommlett, Expedition to the Barrier Peaks, Tomb of Horrors and of course Keep on the Borderlands, likely the most played Dungeons & Dragons adventure of all time. While some of his adventures, such as Expedition to the Barrier Peaks and Tomb of Horrors, were at least significantly the work of others (Kask and Lucien respectively), though Gygax undoubtedly had a hand in them as well. His output was prodigious and his foundational adventures are still well known today. I’d argue that adventure creation, rather than rules of mechanics, was Gygax’s greatest strength as a designer. With Arneson, Gygax wrote a system of adventure or dungeon design into the 1974 edition of Dungeons & Dragons, but he didn't follow it long, and certainly not in his published work, instead innovating and diverging from his own early advice to pioneer a new style of adventure design. Yes, his most important contribution to the hobby was likely organization and promotion - and the hobby of role playing games owes him a great amount of credit, perhaps even its existence for his efforts there - but Gygax’s adventure design still stand tall a half-century later, and it's full of useful lessons and techniques.
Gygax & Design
Like all good designers, especially early in the hobby, Gygax’s design has its own flavor and concerns. For Gygax adventure design is most often focused on the nature of the forces opposed to the players and potential environmental factors or conflict among these enemies that the players can exploit. He was first a wargamer, and his signature adventures are far more “sieges” or “infiltrations” then they are “explorations”, though this is not universal or absolute. Gygax’s adventure writing itself is marked by an relative indifference to map design, and the use of sparse keys that offer the minimum of environmental detail while focusing on the monsters encountered and their military strategies or behavior.

Gygax designed a variety of scenarios over his long career, but the central challenge in Gygax’s best known adventures, at least the ones where he’s clearly the sole designer (again, not Tomb of Horrors or Expedition to the Barrier Peaks) is one of military tactics or strategy. In a Gygax adventure the party will succeed if they can outwit, destroy, suborn, or bypass a hostile, organized force more powerful than them. Examples of these forces include the giants in the Against the Giants modules, the humanoid tribes in Keep on the Borderlands, or the mountain giant and his flunkies in the Forgotten Temple of Tharizdun. In all cases the party is unlikely to survive a direct confrontation with the forces against them, and instead needs to use schemes, things they discover about and within the dungeon, or subterfuge to overcome them. Often these solutions require that the party access the enemy base/dungeon without alerting its guards, and then conduct a campaign of theft, assassination, and sabotage within.
The siege or infiltration scenario is natural enough, it’s the sort of thing that naturally evolves from skirmish wargaming -- where one wants to justify both a small group of characters and provide their player(s) agency within the context of a larger military conflict. In 2002, during a Question & Answer session on ENworld’s bulletin boards Gygax rejected idea that Dungeons & Dragons had an exact analogue to military siege scenarios, stating that “no actual D&D game module I've ever seen has taken the base, sieges, to the 'commando' raid stage, either in infiltrating a fortress of for breaking out of one to wreak havoc on the besiegers lines.” However, Gygax liked the concept, and claimed to be writing an adventure based on the scenario of infiltrating a fortress during a siege … his rejection of the idea appears more one of exacting terminology than to the suitability of the design itself. Setting aside the context of a strictly military “commando raid”, it’s obvious that Gygax often wrote adventures centered on infiltration as a part of a violent conflict - ambushes, evasion, assassination, and sabotage. While there are elements of dungeon exploration involved, including entire adventures written using other design forms, the infiltration scenario is distinct, and Gygax perfected it, even creating special tools to run it more efficiently.
When interrogating this style of design, the first thing to notice is that the primary source of tension in a Gygaxian Siege is not supply depletion or the pure risk of random encounters, but the larger risk of an alarm being raised. Once the fortress is alerted the adventure will change almost fundamentally as the enemy forces begin to actively patrol, reinforce each other and gather at choke points. A siege adventure is not usually a race against the steady depletion of character resources like the traditional dungeon crawl, but an effort to get as close to one’s goals before the alarm is raised and the enemy begins to hunt the party.
