My pick depends on the work you want to skip - not the size of the book. I’d choose Abomination Vaults for dungeon prep, Masks of Nyarlathotep for investigative resources, or Curse of Strahd for player-led gothic travel.
I compare all three by prep, maps and handouts, campaign continuity, and player choice. A 666-page campaign with more than 100 handouts can supply plenty of material - and still demand hours of reading.
Quick Comparison
| Campaign | Prep | Maps and Handouts | Continuity | Player Choice |
|---|---|---|---|---|
| Abomination Vaults - Pathfinder 2e | Lower session prep; learn rooms and creatures | Strong tactical maps; VTT extras sold separately | One dungeon and a recurring town base | Routes, retreats, and faction talks |
| Masks of Nyarlathotep - Call of Cthulhu | Heavy reading and clue tracking | More than 100 handouts, plus maps and references | One conspiracy links international chapters | Follow leads across countries |
| Curse of Strahd - D&D | Prepare travel, NPCs, and uneven threats | Useful maps; some gaps to fill | Strahd connects locations; the GM tracks his reactions | Choose destinations, allies, and dangers |
My advice: budget reading time separately from session prep. Before committing, agree on who keeps notes, check how players can find needed clues, and set boundaries for horror content. Published support reduces some work. It doesn’t remove it.

Top 5 Most Inspiring RPG Adventures
1. Pathfinder Second Edition - Abomination Vaults
Abomination Vaults is a level 1–10 megadungeon centered on the Gauntlight. It’s available in three volumes or as a 288-page hardcover.
Its strongest support covers dungeon prep, maps, and tracking changes during play.
GM Prep and Navigation
Keyed rooms reduce invention, but you still need to read ahead. The adventure supplies encounters, hazards, treasure, enemies, and details about the surroundings. That means less encounter design, though you’ll still need to prepare for the party’s route.
Before play, read the likely route, adjacent rooms, and creatures with unusual abilities. Keep a separate map reference handy: the dungeon has multiple floors and plenty of connections.
Maps and Handouts
The maps support tactical movement and room-by-room play. Still, check doors, cover, elevation, secret passages, and objects players can interact with.
Printed maps need player-facing prep. Online games may also need labeled maps, tokens, lighting, and handouts. Paizo’s Foundry VTT edition includes 11 remastered maps, 15 additional immersive maps, and 225+ high-resolution tokens. Those extras come with the digital release, not the hardcover.
Campaign Continuity
Continuity comes from changing locations rather than a fixed scene order. Use a session log to track cleared rooms, faction shifts, and newly opened paths.
Otari serves as a recurring base, while Belcorra Haruvex’s legacy gives the descent a continuing purpose. The collected edition puts the campaign in one place, but tracking its changing state still falls to the GM.
Player Choice
Players can choose routes, retreat, revisit rooms, and negotiate with dungeon factions. To prepare for that freedom, note each faction’s goals, knowledge, and likely response to intruders.
Best fit: tables that want tactical combat and exploration. If your group wants more social play, build out Otari conversations and faction negotiations with clear stakes.
Abomination Vaults offers a low-prep dungeon campaign, though it’s less suited to heavy clue work. The next example shifts to investigation, handouts, and long-form clue management.
2. Call of Cthulhu - Masks of Nyarlathotep
Where Abomination Vaults cuts dungeon prep, Masks of Nyarlathotep puts the work into tracking clues and managing travel. Chaosium’s seventh-edition Masks of Nyarlathotep is a 666-page campaign packed with support for long-running investigations, including more than 100 handouts, plus maps and reference tools.
GM Prep and Navigation
Cross-references link characters, locations, handouts, and items, while appendices gather spells, tomes, and artifacts. Read the main mystery first, then prepare the current chapter. Keep a clue index showing each lead’s source, destination, and status, with NPC motives alongside it. Organization, rather than encounter design, takes most of the prep work.
Maps and Handouts
Letters, newspapers, journals, and maps put evidence directly into players’ hands. The maps support travel and site exploration, including an 11-by-17-inch world map and maps of specific locations. Before each session, sort likely handouts by where investigators can find them, and keep unrevealed material separate. Track travel time on its own - the maps won’t manage the campaign clock.
Campaign Continuity
The optional 1921 Peru prologue connects the investigators to Jackson Elias. The main investigation starts in America in 1925, with chapters in England, Egypt, Kenya, Australia, and China tied to the Carlyle Expedition. Keep a dated travel log, NPC status notes, and a record of unresolved leads. Pair that record with the campaign’s concluding guidance so the ending reflects what investigators accomplished - and what they left unchecked.
Player Choice
Investigators can follow international leads in different orders. Side scenarios add material for groups that pause or stray from the main storyline. Prepare likely destinations rather than treating chapter order as mandatory. If players miss a key lead, offer another believable source instead of forcing them back to one scene. Mark side tracks as optional before play so they don’t bury the main mystery.
Best fit: groups that enjoy interpreting evidence and keeping notes, with a Keeper willing to manage a branching campaign. The next campaign moves from investigation to gothic travel and character-driven danger.
3. Dungeons & Dragons - Curse of Strahd
GM Prep and Navigation
Curse of Strahd covers levels 1–10. Death House can take characters from level 1 to 3, but its deadly encounters make it a poor fit for groups eager to roam Barovia freely. Before play, note each location’s intended level and flag early destinations that could overwhelm the party. Prep the current location and one or two likely next stops, and read Castle Ravenloft before the finale.
Maps and Handouts
Regional and location maps lay out Barovia’s geography. Letters and other documents help set its horror tone. Label each scene as map provided, theater of the mind, or needs a map. Then prepare only the missing maps. Keep travel distances, encounters, and safe rest points in one place so journeys don’t turn into on-the-fly bookkeeping.
Campaign Continuity
Strahd drives continuity; the GM tracks his responses. His recurring threats and manipulation tie locations together without forcing the party onto a fixed route. Track each major NPC’s goals, alliances, and relationship with Strahd, updating those notes when the party intervenes. Before each session, decide what Strahd knows and how he might use the party’s latest choices against them.
Player Choice
The Tarokka reading sets the locations of major treasures, an important ally, and the final confrontation. Record the results before sharing those clues, check the route’s difficulty, and give players enough guidance to turn cryptic readings into places they can find.
Barovia gives players meaningful choices about routes and factions, but encounters don’t automatically match the party’s level. Use warnings and visible consequences to signal danger, while leaving room for retreat or negotiation. The comparison below shows how those tradeoffs stack up against the other two campaigns.
Compare Prep, Resources, Continuity, and Player Choice
Pick the campaign whose support matches the work your table wants to avoid.
Treat these ratings as a decision guide, not a quality ranking: High means strong, usable support; Moderate means useful support that still leaves plenty of GM work; Limited means a heavy GM workload.
| Campaign | GM Prep and Navigation | Maps and Handouts | Campaign Continuity | Player Choice |
|---|---|---|---|---|
| Abomination Vaults | High - Clear dungeon structure, though routes and threats still need prep. | High - Strong tactical floorplans. | High - One location and one base make continuity easy to track. | High - Players choose routes, negotiate, and retreat within a contained dungeon. |
| Masks of Nyarlathotep | Moderate - Cross-references help, but tracking clues and travel takes major GM organization. | High - More than 100 handouts, maps, and references. | High - A single conspiracy connects the chapters. | High - Investigators can follow clues and visit major locations in different orders. |
| Curse of Strahd | Moderate - The open structure shifts prep toward travel and encounter timing. | Moderate - Useful maps, though many tables still need extras. | Moderate - The setting and villain connect the episodes, but pacing depends on the party’s route. | High - Players choose destinations, leads, and which dangers to confront. |
Prep: initial reading versus session work. In Abomination Vaults, session prep centers on room connections, hazards, monster abilities, and retreat routes. Masks needs more advance reading to understand how discoveries connect across chapters. Cross-references cut down on searching - not reading. Curse of Strahd sits between the two, with prep shaped by where the party goes.
Resources and continuity. Index handouts and maps by location, then track what changes. For Abomination Vaults, that means cleared rooms and faction shifts. For Masks, track discovered leads and unresolved questions. For Curse of Strahd, track NPC responses. More resources don’t remove that GM work.
Player choice. Abomination Vaults focuses on decisions within a contained dungeon, so prepare for how factions respond. Masks supports nonlinear clue pursuit, which means preparing alternate sources for evidence players might miss. Curse of Strahd offers open gothic travel, making unexpected destinations a bigger part of session prep.
The next section breaks down what each campaign still leaves for the GM.
Strengths, Limits, and Remaining GM Work
Each adventure gives the GM a different set of tools - and leaves different work to do before and during play.
| Campaign | Main Advantages | Remaining GM Work | Poor Fit |
|---|---|---|---|
| Abomination Vaults | Clear dungeon structure, recurring threats, traps, and one home base. | Review creature abilities; track dungeon geography, faction activity, room connections, pacing, and the effects of retreating or bypassing encounters. | Tables that want frequent changes of scenery, long-distance travel, or mostly social play. |
| Masks of Nyarlathotep | A long-form investigation with extensive handouts, maps, references, and Keeper support. | Turn long chapters into session notes; plan for missed evidence and different travel routes. | Keepers with little reading time; players who dislike piecing together scattered information. |
| Curse of Strahd | Gothic atmosphere, a strong villain, and a flexible regional sandbox. | Organize travel references, NPC agendas, travel order, and encounter timing when the party takes an unexpected route. | Groups that want a fixed route or a bright heroic tone. |
The biggest risk in investigative play isn't missing pages. It's missing a clue path. Even with published support, play can stall if the group can't reach the next useful clue.
Check clue paths, not just handout counts. Separate must-have information from optional background. For every conclusion players need to reach, note two or three independent ways to get there and whether each requires a roll. Several clues tied to the same failed check still leave one point of failure. Record each conclusion, its sources, and what happens if a source becomes unavailable.
Before play, set lines and veils and choose an in-play safety tool for all three campaigns. This belongs in GM prep. Abomination Vaults includes grotesque threats and dungeon terror; Masks focuses on cosmic and psychological horror; Curse of Strahd includes coercion, violence, and oppressive villainy. Ask which subjects should stay out of the game and which can happen off-screen. Choose a tool such as the X-card or Script Change for use during play. Shorten, reframe, or cut sensitive scenes - published content isn't mandatory.
Which Campaign Fits Your Table?
Choose the campaign that fits how your group likes to play - and how much prep your GM can keep up with.
| Table Need | Best Fit Among These Three | Main Caveat |
|---|---|---|
| Tactical, location-based play with low-to-moderate session prep after the first read-through | Abomination Vaults | Even predictable dungeon play requires learning the layout and encounters. |
| Long-form investigation with time for heavy Keeper prep | Masks of Nyarlathotep | The Keeper must still track clues, scope, and chapter flow. |
| Gothic atmosphere and player-directed regional travel | Curse of Strahd | The DM needs to organize destinations, travel, and encounter order. |
None runs itself. Before committing, agree on who will track campaign notes and how much preparation the GM can handle over time. Weigh dungeon continuity, investigative support, and setting-driven freedom against what your table can take on.
FAQs
Which campaign is easiest for a first-time GM?
A mini-campaign of about 2–12 sessions is the easiest starting point for a first-time GM. A clear, linear story arc and GM-led structure keep the story connected while requiring less prep and a shorter commitment than a long campaign.
For the lowest-risk option, choose a 2–6-session adventure with one endpoint. Prep only for the next session.
How can I estimate a campaign’s total prep time?
Start with your campaign format, session count, and story complexity. Long campaigns call for prep over a longer stretch. Mini-campaigns need more focused work, while one-shots usually take less prep - often around 2 hours.
Your prep style and desired level of detail matter, too. Pre-made adventures generally cut down the workload, but budget extra time to customize NPCs or adjust encounters. Plan for a campaign that fits your group’s schedule.
Can I adapt these adventures for a smaller group?
Yes. Published adventures give you a framework, not a rigid script. You can change them to suit your table.
Adjust encounter difficulty to fit what your players’ characters can handle, add or remove NPCs, or build out locations your group wants to explore. Reworking an existing adventure is often easier than starting from scratch. That leaves you more time to focus on pacing and encounters that keep your group engaged and work for your player count.
