Lessons from Running My Own D&D 5e Campaign — A Multi-Part Guide for GMs

Part 1 — Group Size and Why “Bigger” Isn’t Always Better

• Observation: In the realm of tabletop role-playing games, the ideal group size tends to hover around 3 to 5 players. This number strikes a balance that fosters engagement and interaction among participants. When groups swell to 8 to 12 players, the dynamics of the game can shift dramatically, turning what should be an exciting and fast-paced combat encounter into a tedious slog. The increased number of players often leads to longer wait times for turns, which diminishes each player's involvement and reduces the overall enjoyment of the game. Additionally, logistical challenges arise, such as coordinating schedules and managing the flow of the game, which can detract from the immersive experience that tabletop RPGs are meant to provide.

• Problems I saw: In my experience with larger groups, I observed several significant issues that consistently arose. For instance, turns could take anywhere from 30 to 60 minutes, which not only slows down the pace of the game but also leads to disengagement among players who are waiting for their turn. Scheduling conflicts become more pronounced as more people are involved; it can be challenging to find a time that works for everyone. This often results in quiet players feeling overshadowed or even disappearing from the game entirely, leading to an imbalance in participation. Furthermore, the burden of managing a large group can lead to DM burnout, where the game master feels overwhelmed by the demands of keeping the game flowing smoothly.

• Practical fixes: To address these challenges, there are several practical solutions that can be implemented. One effective approach is to split the group into two smaller parties, each consisting of 4 to 6 players. This not only enhances individual participation but also allows for more focused storytelling and character development. Another option is to adopt a West Marches-style opt-in schedule, where players can choose which sessions to attend, thus allowing for a more flexible and manageable gaming experience. Additionally, limiting session rosters and rotating players can help ensure that everyone gets a chance to participate without overwhelming the game master or the narrative.

• Quick rule: If you find yourself in the position of needing to run a large table despite the inherent challenges, it becomes crucial to enforce strict time limits for decision-making. This encourages players to think quickly and keeps the game moving at a brisk pace. Implementing group initiative can also streamline combat, allowing players to act collectively rather than waiting for each individual turn. Furthermore, delegating administrative duties, such as tracking initiative or managing rules clarifications, can alleviate some of the burden from the DM, making the overall experience more enjoyable for everyone involved. Additionally, changing combat to "theater of the mind" works incredibly well and keeps everyone engaged, speeds up pacing, and gives everyone a chance to tell the group what their action looks like instead of relying on dice outcomes.

  
  

Part 2 — Concrete Tools to Manage Large Groups

• Group initiative: Implementing a system where all player characters (PCs) act simultaneously before all monsters take their turns can significantly streamline gameplay. This method not only accelerates the flow of the game but also minimizes the burdens of bookkeeping that can often slow down sessions. By allowing players to discuss strategies and coordinate their actions as a team, it fosters a collaborative environment. Furthermore, this approach enables the Dungeon Master (DM) to maintain a faster pace, ensuring that the focus remains on the narrative and engagement rather than on the mechanics of turn-taking.

• Time boxing: Introducing a time limit of 20–30 seconds for players to declare their actions during combat can greatly enhance the efficiency of gameplay. Utilizing visible timers, such as a digital clock or a sand timer, creates a sense of urgency and encourages players to think quickly about their decisions. This method not only keeps the game moving at a brisk pace but also adds an element of excitement and tension, as players are aware that they have a limited window to make strategic choices. Moreover, it can help prevent analysis paralysis, where players may otherwise take too long to decide, thus enhancing overall engagement and participation.

• Delegation: A practical approach to managing large groups involves delegating specific responsibilities to players. By assigning tasks such as initiative tracking, damage tracking, and condition monitoring to different players, the DM can alleviate some of their workload. This delegation not only empowers players by giving them a role in the management of the game but also fosters a sense of ownership and investment in the outcome of the session. Each player can take turns in these roles, ensuring that everyone remains engaged and attentive, while also distributing the cognitive load that comes with managing complex combat scenarios.

• If things still bog down: In situations where combat or gameplay continues to slow down despite implementing the above strategies, consider staging combat as “special operations.” This approach focuses players on key targets, creating a sense of urgency and importance around specific objectives. By narrowing the scope of their actions, players can concentrate their efforts on critical threats, which can lead to quicker resolutions. Alternatively, abstracting mass fights into narrative outcomes can also be an effective tool. Instead of detailing every action in a large-scale battle, the DM can summarize the events, allowing players to engage with the story without getting bogged down in minutiae. This narrative abstraction can preserve the excitement of the encounter while keeping the game flowing smoothly.

  
  

Part 3 — Collaborative World-Building That Actually Works

• Start with session zero: co-create a home town, a few organizations, and stakes players care about. This initial gathering is crucial as it sets the tone for the entire campaign. During session zero, encourage each player to share their character concepts, backgrounds, and motivations. As the group discusses these ideas, collaboratively design the home town, ensuring it reflects the interests and backgrounds of the characters. Consider incorporating various organizations that can serve as allies, antagonists, or neutral parties, which can create rich narrative threads. Establishing stakes that resonate with the players enhances their investment in the story, making them feel like active participants rather than passive observers.

• Use mechanics that invite input: ask for “three truths,” blanks in backstories, or let players name NPCs/locations. These techniques not only foster collaboration but also empower players to shape the narrative. For instance, the “three truths” method allows players to contribute significant aspects of the world or their characters that can influence the unfolding story. Leaving blanks in backstories encourages players to fill in the gaps, creating opportunities for future plot developments. Allowing players to name NPCs or locations gives them ownership of the world, making it feel more personal and engaging. This shared authorship can lead to unexpected and delightful twists in the narrative.

• Tools I used: The Quiet Year-style mapping, Deck of Worlds brainstorming, and a lore-notes slip system so players can write small details that I later weave in. The Quiet Year-style mapping is particularly effective for visualizing the world and its various facets, as it allows players to collaboratively draw and annotate the geography, which can lead to interesting discoveries about the setting. The Deck of Worlds is a brainstorming tool that can spark creativity and generate ideas for locations, factions, and events. Meanwhile, the lore-notes slip system enables players to jot down details they wish to see incorporated into the story, which I can later weave into the narrative seamlessly. This approach not only enriches the world but also ensures that players feel their contributions are valued and acknowledged.

• Rule of thumb: build only what you need; avoid “worldbuilder’s disease.” Make the world reactive, not encyclopedic. It’s easy to fall into the trap of creating an overly detailed world that may never see the light of day in actual gameplay. Instead, focus on developing elements that are immediately relevant to the players and their characters. This means prioritizing the aspects of the world that will have a direct impact on the story and the characters’ journeys. A reactive world responds to the players’ actions and decisions, creating a dynamic environment that evolves with the narrative. This approach fosters a sense of agency and excitement, ensuring that players remain engaged and invested in the unfolding story.

  
  

Part 4 — Sandbox Design: Preparing a Living World, Not a Script

• Core idea: prep situations, not plots. In this approach, the emphasis is placed on crafting a dynamic environment where players can interact with various elements rather than following a predetermined storyline. This involves building intricate factions with distinct goals, motivations, and conflicts that can engage players in meaningful ways. Each faction should have its own history, relationships with other factions, and a set of resources that they can leverage or compete over. Additionally, creating modular locations that can be explored, each with its own unique features and potential encounters, allows players the freedom to choose their paths. Establishing a “home base” area where players can retreat, gather information, or prepare for their next ventures is crucial; this space serves as a hub for social interactions and strategic planning, enhancing the feeling of a living, breathing world.

• Structures that work: hexcrawl or point-crawl for exploration, or a mega-dungeon as a central hub. The hexcrawl method involves mapping out a large area divided into hexagonal sections, each representing a different terrain or location that players can explore. This format encourages players to chart their own course, fostering a sense of adventure and discovery as they uncover the secrets of the world. Alternatively, point-crawl systems offer a more structured approach, where players navigate between key locations connected by pathways, allowing for focused exploration while still maintaining an open-world feel. A mega-dungeon can serve as a central hub, filled with layers of complexity, challenges, and treasures, providing a focal point for players to engage with the world. This dungeon can be designed to evolve over time, with factions vying for control or new threats emerging, ensuring that players remain invested in their exploration.

• Keep momentum: populate the world with competing factions and ongoing events so players’ choices produce visible consequences. To maintain engagement and excitement, it is essential to create a vibrant world where player actions have tangible effects. This can be achieved by introducing multiple factions that have conflicting interests, allowing players to align with or oppose them, leading to shifting power dynamics. Additionally, implementing ongoing events—such as political upheavals, natural disasters, or economic changes—can serve as catalysts for player decision-making. When players see that their choices lead to real changes in the world, whether it be the rise or fall of a faction, the outcome of a conflict, or the state of the environment, it reinforces their agency and investment in the narrative.

• Limit scope: develop the immediate sandbox thoroughly; use modular “nuggets” for unexpected directions. While it may be tempting to create an expansive world filled with endless possibilities, focusing on a smaller, well-developed area can lead to richer interactions and deeper storytelling. By thoroughly fleshing out the immediate sandbox, including its history, culture, and key players, players can immerse themselves in the intricacies of the environment. Furthermore, the use of modular “nuggets”—small, self-contained story elements or encounters that can be introduced at any time—allows for flexibility in the narrative. These nuggets can serve as surprises that lead players down unexpected paths, enriching the experience without overwhelming the core structure of the sandbox. This balance between depth and adaptability ensures that the world remains engaging and responsive to player actions.

  
  

Part 5 — One-Shots and Side Episodes — How to Use Them Well

• Best uses: One-shots and side episodes serve as excellent filler between main sessions, providing a unique opportunity to delve deeper into the narrative and character dynamics. They can be particularly effective for flashbacks that reveal crucial backstory elements or pivotal moments that shaped the characters' motivations and relationships. Additionally, these episodes can focus on side characters, allowing players to explore the lives and stories of those who may not always take center stage in the main campaign. This can foster a richer understanding of the game world and its inhabitants. Furthermore, one-shots can be utilized to explore the broader history of the game world, shedding light on significant events, legendary figures, or ancient conflicts that have left their mark on the present. This not only enhances the lore but also provides players with a sense of continuity and depth in their gaming experience.

• Design tips: When crafting a one-shot or side episode, it is essential to have a clear structure in mind. Aim for 3–4 distinct scenes that drive the narrative forward and maintain player engagement. Each scene should serve a purpose, whether it’s developing a character, advancing the plot, or providing critical information. Fast hooks are crucial; they should immediately grab the players' attention and immerse them in the story. This can be achieved through intriguing scenarios, unexpected twists, or compelling character interactions. Additionally, ensure that the episode has a decisive ending that brings closure to the narrative, leaving players with a sense of accomplishment and satisfaction. It is also important to consider the rewards players receive from the session. These should be meaningful but balanced, ensuring they do not disrupt the overall campaign's power dynamics or narrative flow. Rewards can include unique items, character development opportunities, or insights into the larger plot, all while maintaining equilibrium within the ongoing story.

• Integration tricks: To make a one-shot feel cohesive with the main campaign, it is beneficial to incorporate familiar NPCs that players already know and love. This not only helps to establish a sense of continuity but also provides an emotional connection that can enhance the overall experience. Shared themes are another effective integration strategy; by echoing motifs or conflicts present in the main storyline, the one-shot can feel like a natural extension of the larger narrative. Additionally, weaving relevant lore into the one-shot can enrich the players' understanding of the game world, making them feel more invested in the overarching plot. This could involve referencing past events, utilizing artifacts from previous sessions, or exploring locations that have significance in the main campaign. By carefully crafting these connections, the one-shot can seamlessly blend into the existing narrative, providing players with an engaging and immersive experience that feels integral to their journey.

  
  

Part 6 — Share the Load: Player Tasks and the Assistant GM

• Assign roles: initiative tracker, rules specialist, map-maker, loot manager, lore-keeper. These roles are crucial in enhancing the gameplay experience for everyone involved. The initiative tracker is responsible for keeping track of the turn order during combat, ensuring that the game flows smoothly and that players are aware of when their turns are approaching. The rules specialist can assist in clarifying any rules questions that arise during the session, allowing the game to continue without unnecessary interruptions. The map-maker creates and maintains the visual representation of the game world, which can be especially helpful in combat scenarios where positioning is key. The loot manager keeps track of the items, gold, and resources that the party acquires, ensuring that everyone knows what they have and what is available for use. Finally, the lore-keeper is tasked with maintaining the narrative consistency of the game, recalling important story elements and character backgrounds that can enrich the role-playing experience.

• Benefits: reduces DM burnout, increases engagement, speeds gameplay, and gives players ownership. By distributing these responsibilities among the players, the burden on the Dungeon Master (DM) is significantly lightened, which can help prevent burnout that often accompanies the role of a sole DM. When players take on specific tasks, they become more invested in the game, leading to heightened engagement and enthusiasm. This collaborative approach not only speeds up gameplay by allowing for more streamlined processes during sessions but also fosters a sense of ownership among players. When players feel that they have a stake in the game's progression and mechanics, they are more likely to contribute actively to the story and the overall gaming experience.

• Assistant GM: have a co-GM for rule lookups, NPCs, or running a second group if you split parties. The role of an Assistant GM can be invaluable, especially in larger groups or complex campaigns. This co-GM can assist with quick rule lookups, allowing the main DM to focus on storytelling and character interactions without being bogged down by the minutiae of game mechanics. They can also take on the responsibility of managing non-player characters (NPCs), which can enrich the game world and provide additional depth to the story. Furthermore, if the party decides to split up to pursue different objectives, the Assistant GM can run a second group, ensuring that all players remain engaged and entertained, rather than having some players sitting idle while others play through a separate encounter.

• Implementation tip: set clear expectations for each role, rotate them, and reward reliability. To effectively implement this structure, it is essential to establish clear expectations for each assigned role. This clarity ensures that everyone understands their responsibilities and how they contribute to the overall success of the game. Additionally, rotating roles among players can provide everyone with the opportunity to experience different aspects of the game, enhancing their skills and understanding of the mechanics. This rotation can also prevent any one player from feeling overwhelmed by a single role for too long. Lastly, recognizing and rewarding reliability—whether through in-game benefits, acknowledgment during sessions, or small tokens of appreciation—can encourage players to take their roles seriously and contribute positively to the gaming environment.

  
  

Part 7 — Common Pitfalls and How I Avoided Them

• Info dumps: One of the most common pitfalls in storytelling, especially in role-playing games, is the tendency to overwhelm players with extensive lore all at once. These info dumps can lead to confusion and disengagement, as players may feel lost in a sea of details that they cannot fully absorb. To avoid this, I focus on revealing important aspects of the lore gradually through gameplay. This approach allows players to discover the world organically, making each piece of information more impactful and memorable. For instance, instead of presenting a lengthy history of a kingdom in a single session, I weave it into the narrative through character interactions, environmental storytelling, and quests that reveal the culture and history in a more digestible manner.

• Waiting to start: Another common mistake is delaying the start of the game until every detail is perfect or when the world feels completely fleshed out. While having a strong home base is important, I have learned that it is often more beneficial to begin the game sooner rather than later. Starting with a foundational setting allows me to build outward as the sessions progress, adapting and expanding the world based on player actions and decisions. This not only keeps the momentum going but also encourages player investment in the world, as they can see their influence on the unfolding story. By treating the initial setting as a launching pad, I can introduce new elements and locations as the campaign evolves, creating a dynamic and engaging experience.

• Monolithic cultures: A frequent oversight in world-building is the creation of cultures or factions that are overly simplistic or monolithic. This can lead to stereotypes and a lack of depth in the narrative. To counter this, I strive to develop complex societies that are flawed and interconnected, showcasing a range of perspectives within each group. For instance, rather than depicting a faction as purely good or evil, I explore their motivations, internal conflicts, and varying ideologies among their members. This approach not only enriches the narrative but also provides players with meaningful choices and dilemmas that reflect the complexities of real-world cultures.

• Magic consequences: In many fantasy settings, magic is a powerful tool that can dramatically alter the fabric of society. However, neglecting to account for how magic influences economics, social structures, and daily life can lead to a world that feels inconsistent or unrealistic. I make it a priority to consider the implications of magic on various aspects of the world. For example, if healing magic is readily available, how does that affect the healthcare system? What are the economic ramifications of a society where certain spells can produce food or resources? By exploring these questions, I create a world that feels cohesive and believable, allowing players to immerse themselves fully in the narrative.

• Proscriptive world-building: Lastly, one of the biggest mistakes a game master can make is to impose rigid structures that limit player creativity and agency. It is essential to provide players with the freedom to carve their own paths and make meaningful choices within the world. I avoid proscriptive world-building by leaving room for player input and encouraging them to develop their characters and backstories in ways that fit organically into the narrative. By fostering an environment where players can express their creativity, I enhance their engagement and investment in the story, leading to a richer and more collaborative gaming experience.

  
  

Part 8 — Final Lessons & Actionable Checklist for GMs

• Start small and iterate: launch with a tight sandbox and expand. Begin your campaign in a well-defined, manageable area where players can explore and engage with the world without feeling overwhelmed. This initial sandbox should be rich in detail but limited in scope, allowing players to familiarize themselves with the mechanics and narrative. As the players become more comfortable and invested in the game, gradually introduce new locations, plot lines, and challenges, expanding the world organically based on their actions and interests. This iterative approach not only keeps the game focused but also allows for player-driven storytelling, making the experience more engaging and personalized.

• Prioritize player input: session zero + in-play prompts = buy-in. Establishing a strong foundation of player engagement is crucial for a successful campaign. A session zero is an excellent opportunity to discuss character backgrounds, expectations, and preferences, ensuring that everyone is on the same page. During gameplay, utilize in-play prompts to invite feedback and encourage players to voice their ideas and desires for the story. This ongoing dialogue fosters a sense of ownership among players, making them feel valued and invested in the unfolding narrative. By actively incorporating their input, you create a more immersive and collaborative gaming experience.

• Share responsibility: assign tasks and, if possible, appoint an assistant GM. Running a game can be a significant undertaking, and sharing the load can enhance the experience for both you and your players. Consider delegating specific responsibilities, such as tracking initiative, managing NPCs, or handling rules clarifications. This not only lightens your burden but also empowers players to engage more actively in the game. If your group is large or if you have a particularly ambitious campaign, appointing an assistant GM can be invaluable. This individual can help with logistics, facilitate side quests, or provide additional narrative depth, allowing you to focus on the overall story and player interactions.

• Plan for scale: split groups or run opt-in sessions rather than stretching one table too large. As your campaign grows in popularity, be mindful of the challenges that come with larger groups. Instead of cramming too many players around one table, consider splitting the group into smaller factions or running multiple sessions that players can opt into based on their availability and interest. This approach not only maintains the quality of gameplay but also ensures that each player receives ample attention and opportunity to shine. Smaller groups can foster deeper character development and more meaningful interactions, enhancing the overall experience for everyone involved.

• Keep combat snappy: group initiative, time limits, and delegation are your friends. Combat can often bog down the pace of a game if not managed effectively. To keep the action flowing, consider implementing group initiative rolls, where players can act together, reducing the time spent on individual turns. Establishing time limits for decision-making during combat can also help maintain momentum. Encourage players to delegate certain tasks, such as tracking health or managing spell slots, to streamline the process. By keeping combat dynamic and engaging, you ensure that players remain invested and excited about the challenges they face, rather than feeling frustrated by drawn-out encounters.

• Use one-shots intentionally: tight, themed, and consequential. One-shot adventures can serve as powerful tools for introducing new players to the game, testing out new mechanics, or exploring unique storylines without the commitment of a long-term campaign. To maximize their impact, ensure that these one-shots are tightly structured, with a clear theme and purpose. Every element should contribute to the overarching narrative, and the choices players make should feel significant and consequential. This intentional design not only provides a satisfying experience in a short time frame but also leaves players eager for more, potentially leading to future campaigns or extended adventures.

Closing thought: A truly great campaign is less about meticulously preparing every single detail in advance and more about the strategic design of systems and social structures that empower players to actively shape the world around them. The essence of a successful campaign lies in creating an engaging framework that allows players to explore, interact, and influence the narrative while you, as the Game Master, maintain the underlying engine that drives the story forward. This approach not only fosters player agency but also encourages creativity and collaboration, resulting in a dynamic and evolving game experience that can adapt to the players' choices. In this context, it becomes essential to establish a flexible narrative structure that can accommodate unexpected player actions and decisions. By designing a world rich with lore, intriguing characters, and complex political landscapes, you provide players with the tools they need to engage deeply with the setting. This means crafting a living world that reacts to their actions, where choices have consequences, and where the players feel their contributions are meaningful. Moreover, implementing systems that facilitate player input can enhance their investment in the campaign. This might include allowing players to develop their own backstories that intertwine with the main plot, creating opportunities for them to introduce personal stakes into the narrative. Additionally, incorporating mechanics for player-driven events or community-building elements can further enrich the campaign, making it a collaborative storytelling experience rather than a one-sided narrative. If you are interested, I can certainly convert this concept into a series of blog posts that delve deeper into each aspect of campaign design. Each post could explore different elements such as world-building, character development, and player agency, complete with intros to set the stage, estimated word counts for each entry, and suggestions for relevant images or handouts that would enhance the reader's understanding and engagement with the topic. This approach would not only provide valuable insights but also serve as a practical guide for Game Masters looking to elevate their campaigns to new heights.
