Session Zero Tips for Setting Expectations

Before starting a tabletop RPG campaign, Session Zero is crucial for aligning expectations between the Game Master (GM) and players. This meeting sets the tone, defines gameplay style, and ensures everyone is on the same page. Skipping it often leads to campaigns falling apart early. Here’s what to cover:

• Campaign Premise & Play Style: Define the story, tone, and pacing. Use examples like "gritty political thriller" or "lighthearted dungeon crawl" to clarify expectations.
• Character Creation Rules: Decide on rulebooks, ability score methods, and starting levels. Explain any restrictions to fit the narrative.
• Party Connections: Build relationships between characters to avoid disjointed storylines. Use shared goals or histories for cohesion.
• Content Boundaries: Discuss sensitive topics and introduce tools like Lines, Veils, and X-Cards for player comfort.
• Scheduling & Attendance: Agree on a fixed schedule, quorum rules, and how to handle absences.
• House Rules & Procedures: Clarify custom rules and how to resolve disputes.
• Table Behavior: Set guidelines for phones, side chats, and conflict resolution.
• Campaign Reference Sheet: Create a shared document summarizing all agreements for easy access.

This preparation ensures smoother gameplay, stronger party dynamics, and a campaign that’s enjoyable for everyone.

Top 5 Things to Prepare for Session Zero in D&D (For DMs & Players!)

1. Define the Campaign Premise and Play Style

Start your Session Zero by delivering a strong campaign pitch. This should include a brief summary of the central conflict, the starting location, and the overall theme. Keep it concise - just enough to spark curiosity without giving away too much.

But don’t stop at the plot. Tone and play style are just as important. If the tone doesn’t match expectations, it can throw the whole campaign off track. Imagine the GM planning a gritty political thriller while the players expect a lighthearted dungeon crawl - it’s a recipe for frustration. Being upfront about the mood helps everyone align their characters with the world being created.

One way to establish tone quickly is by using media references. Mentioning a familiar book, movie, or TV show can instantly set the vibe. For example, describing the campaign as "like The Witcher - morally gray, brutal, and full of tough decisions" is far more vivid than simply calling it "dark and gritty".

"Session Zero is where you decide if your campaign starts like a symphony… or a bar brawl." - Dave "The Kegslayer", Dungeon Master

Once tone and style are clear, you can naturally transition into discussing game mechanics and pacing. This clarity ensures everyone knows what kind of game they’re signing up for.

Play Style and Pacing Matter

Be upfront about play style and pacing as well. Will the game focus on tactical grid combat or lean more toward "Theater of the Mind" storytelling? Is it a sandbox where players dictate the direction, or a structured, plot-driven experience? Will the GM stick strictly to Rules as Written (RAW), or embrace the Rule of Cool for more flexibility? These decisions shape character creation and set clear expectations for the group.

Play Style Element	Examples
Tone	Heroic, gritty, political, horror, comedic
Pacing	Combat-heavy vs. roleplay-focused; frequency of downtime
Agency	Linear/plot-driven vs. sandbox/open-ended
Rules Philosophy	Rules as Written (RAW) vs. Rule of Cool

To keep everything organized, consider creating a Campaign One-Sheet. This single-page document summarizes the setting, tone, house rules, and major factions. It’s a handy reference for players during character creation and helps keep everyone on the same page.

2. Set Character Creation Rules

Once the campaign's tone and play style are nailed down, the next step is setting clear rules for character creation. Start by deciding which rulebooks players can use. A good starting point is the core rulebook, as it provides the most balanced and well-tested options. From there, you can decide whether to allow supplemental books on a case-by-case basis.

"The safest options are the common choices from Player Core. If players want to use common options from other books or uncommon or rare options, review those options to see if any of them conflict with the style of campaign." - GM Core

For example, if you're running a low-magic setting, you might restrict certain classes like Sorcerers or Warlocks to fit the narrative. Always explain the reasoning behind any restrictions. Instead of simply saying "no", let players know that "magic is rare and feared in this world, so arcane casters draw unwanted attention." This approach helps players immerse themselves in the setting rather than feeling like they're being arbitrarily limited.

Beyond rulebooks, establish the technical basics before anyone starts filling out a character sheet. Decide on key mechanics like:

• Ability score generation method: Will you use Standard Array, Point Buy, or rolling?
• Starting level: What level will characters begin at?
• Hit point calculation: Will hit points be rolled or fixed?

These decisions directly impact how characters stack up against each other, so setting them early avoids confusion or imbalance later on.

It's also a good idea to offer a grace period for players to tweak skills, abilities, or ancestry if their initial choices don't work out as planned. For newcomers, pairing them with experienced players during character creation can make navigating the rulebooks much easier.

With these guidelines in place, you're ready to move on to building strong party bonds and crafting compelling backstories.

3. Build Party Connections and Backstories

Campaigns often falter when characters lack a reason to stick together. Collaborative character creation during Session Zero can prevent this issue entirely. Whether you're meeting in person or online, building characters as a group ensures everyone has a stake in the party's shared story.

Each character should have at least one tie to another member of the group. These connections can be simple yet meaningful - maybe they served in the same military unit, grew up in the same small town, or one character saved another during a dangerous mission. These shared experiences create an immediate sense of trust, so you can skip the awkward "why are we even traveling together?" phase in the first session.

"Campaigns that start with pre-established connections between characters start with party cohesion already in place." - Black Lantern Forge

A helpful approach is the "Two Ties" rule: ask each player to define two key elements for their character. One should be a person significant to them (like a mentor, rival, or family member), and the other should be a place they can't forget. This keeps backstories concise and provides the GM with actionable material without needing to comb through lengthy character histories. These connections naturally weave character backgrounds into the campaign's story, making the world feel alive and interconnected.

It’s also important to address the "lone wolf" archetype early on. While it might seem intriguing, a character who "doesn't trust anyone and works alone" can disrupt group dynamics. The goal of Session Zero is to create a unified story, so encourage players to tweak such concepts to better fit the campaign - or adjust the campaign to accommodate them, if possible.

"The character who 'doesn't trust anyone and works alone' won't work. Help players adjust concepts to fit the campaign, or adjust the campaign to fit their concepts." - Anvil & Ink

Here’s a quick look at some connection types that work well for grounding characters in the party:

Connection Type	Example	Benefit
Shared History	Served in the same military unit or academy	Establishes trust and shared terminology
Life Debt	One character saved another during a skirmish	Creates emotional bonds and loyalty
Shared Goal	Both seek to overthrow a corrupt noble	Aligns motivations with the campaign
Familial/Social	Siblings, cousins, or from the same small village	Builds loyalty and shared NPCs

Once these connections are in place, have each player name an NPC tied to their shared background. This provides the GM with instant story hooks and brings the campaign world to life from the start. With these bonds established, your campaign is set to naturally evolve into rich storylines and immersive gameplay.

4. Set Content Boundaries and Introduce Safety Tools

Establishing clear content boundaries and introducing safety tools is a key part of Session Zero. Every player comes to the table with their own sensitivities, and addressing these upfront can prevent issues down the road. As Black Lantern Forge explains:

"Skipping content boundaries in session zero is how a campaign ends up unintentionally hurting a player in session six. Five minutes of explicit conversation prevents months of damage."

Some common areas to discuss include graphic violence, harm to children or animals, sexual content, specific phobias, and heavy themes like torture or slavery. As the GM, sharing your own limits sets the tone and helps normalize open conversations about boundaries. Once these are established, the next step is to introduce tools to uphold them during gameplay.

One widely used tool is Lines and Veils, introduced by Ron Edwards in the Sex & Sorcery supplement for the Sorcerer RPG. A Line represents a firm boundary - content that won’t appear in the game at all. A Veil, on the other hand, allows for sensitive topics to exist in the narrative but keeps them off-screen or implied rather than explicit.

For unexpected situations, the X-Card is another effective tool. This simple mechanism allows any player to pause or adjust the current content without needing to explain or justify their discomfort. The D&D Dungeon Master's Guide emphasizes this approach:

"The signal shouldn't trigger a debate or discussion: thank the player for being honest about their needs, set the scene right, and move on."

For players who may feel shy about speaking up, anonymous pre-session surveys can be a helpful alternative. A Google Form sent out before Session Zero allows participants to privately flag any sensitive topics. When reviewing the results, keep the language neutral - phrases like "we've agreed to keep [topic] out of the game" maintain privacy while ensuring clarity.

Additionally, an Open Door Policy can provide reassurance. This lets players step away from the table at any time, no questions asked, reinforcing a safe and supportive environment. Remember to revisit these tools periodically, especially when new players join or as comfort levels shift over time.

5. Agree on Schedule and Attendance Rules

Once you've nailed down the campaign's content and character guidelines, it's time to tackle the logistics that keep everything running smoothly. Scheduling might not seem like a big deal during Session Zero, but it's the backbone of a campaign's longevity. As Tabletop RPG Authority puts it:

"Session Zero is... the difference between a campaign that runs for two years and one that quietly collapses after session four."

A fixed, recurring schedule is key. Instead of planning one session at a time, lock in a consistent time slot - weekly, biweekly, or monthly. For example, you might agree on "every other Tuesday from 7:00 PM to 10:00 PM". Since most sessions last 3–4 hours, having a clear end time helps everyone balance gaming with their other responsibilities.

Now, let’s talk attendance. Decide on a quorum - the minimum number of players required to hold a session - and plan for what happens when someone can’t make it. For instance, a group of five players might agree to play as long as at least three can attend. If fewer show up, the session gets postponed.

Anvilnink offers this advice:

"Be specific. 'We'll play every other Tuesday, 7 PM to 10 PM. If fewer than three players can make it, we postpone. Otherwise we play.' This clarity prevents future arguments."

You’ll also need a plan for absent players' characters. Here are some common approaches:

Method	Description	Best For
Fade to Background	The character stays in the scene but doesn't actively participate.	Keeping the group together without extra effort.
GM/Player Control	The GM or another player temporarily manages the character.	Games where party balance is critical.
Narrative Removal	The character has a story-based reason to be elsewhere.	Story-driven campaigns with immersive elements.
Pocket Dimension	The character vanishes and reappears later without explanation.	Laid-back, easygoing campaigns.

To keep everyone on the same page, centralize scheduling and communication. Whether you use Discord, WhatsApp, or a shared Google Doc, make sure the agreed schedule is accessible to all players. Include time zone details for online games to avoid confusion.

6. Clarify House Rules and Table Procedures

Once your schedule is set, it's time to ensure everyone is on the same page about how the game will run. House rules and table procedures are the backbone of smooth gameplay, and setting these expectations early helps avoid confusion later.

As Dave "The Kegslayer" from Grim Tavern puts it:

"House rules are fine, but everyone should know them before the goblins hit the fan."

This shared understanding lays the groundwork for a seamless experience. Before Session One, the GM should go over any rule changes or additions. Key topics to address might include whether healing potions require an action or a bonus action, how flanking is handled (flat +2 bonus or advantage), and whether leveling will follow milestones or experience points.

Another important decision is whether to stick with the standard rest system or try a variant like Gritty Realism, which changes short rests to 8 hours and long rests to a full week. This choice can dramatically affect the campaign's pacing and how players manage their resources.

You’ll also want to establish a process for handling rule disputes. Arguments over mechanics are bound to happen, so consider adopting a "quick ruling now, verify later" approach to keep the game moving. As Roll for Two reminds us, "consistency is key." By setting these clear guidelines, you’re building on the foundation of character creation and scheduling, ensuring the campaign stays on track from start to finish.

7. Set Table Behavior and Communication Standards

Once you've nailed down the game mechanics and house rules, it's time to focus on the human side of things - how players interact and communicate during sessions. Establishing clear expectations for behavior at the table can make a world of difference in keeping everything respectful and running smoothly. As Dave "The Kegslayer" from Grim Tavern wisely says:

"Respect at the table builds comfort, and comfort builds better roleplay."

Start by deciding on a phone policy. Will phones be completely off-limits, allowed only for emergencies, or permitted for specific digital tools? Agreeing on this upfront helps reduce distractions. Similarly, think about how to handle side conversations. A good rule of thumb: save the extended chats for breaks. This keeps the focus where it belongs - on the game - and avoids interrupting key moments.

Another important step is setting up a system to manage out-of-character conflicts. Make sure everyone understands the difference between in-character disputes (handled through the game's mechanics) and real-life disagreements. If tension arises mid-session, any player should feel free to call for a quick pause - no explanation required. This "pause button" approach reinforces the idea that the group's well-being comes first, even before the story.

Here's a quick breakdown of common etiquette points to consider:

Etiquette Category	Common Session Zero Decisions
Phones	Away entirely / Face-down / Emergencies only / Breaks only
Side Chat	Allowed if brief / Prohibited during others' turns / Break time
Out-of-Character Conflicts	Call a pause / Address privately / Open-door policy applies
Table Space	Shared snacks / Clean up own trash / No open drinks near maps

8. Share a Campaign Tools and Reference Sheet

When running a campaign, it’s essential to document agreements and details in a way everyone can easily access. Relying on memory alone can lead to confusion. A campaign reference sheet brings together everything - house rules, safety tools, scheduling info - into one central location that players and the GM can refer back to.

"Create a shared note... Everyone has it. Nobody can claim they didn't know." - Roll4Availability

Keep it concise. A single-page guide is ideal for outlining the campaign’s key points. If you need a more detailed document, aim for 4 to 6 pages at most. This should cover the campaign’s premise, setting, rules, logistics, and safety tools. Long documents are less likely to be read or used.

Make sure the reference sheet is stored somewhere accessible to everyone. Options like a shared Google Doc, a Notion page, or a pinned message on Discord work well. This way, it becomes a living document that can be updated as the campaign progresses. Use a versioning system (e.g., Covenant_v1_20260603) so players always know they’re looking at the latest version.

Here’s what a reference sheet should include:

Section	What to Include
Logistics	Session day/time, session length, quorum rules, absence policy, VTT or meeting link
Rules	Game edition, allowed sourcebooks, stat generation method, house rules, death/resurrection mechanics
Safety	Agreed Lines and Veils, X-Card instructions, off-limit topics
World	Campaign pitch, setting "Six Truths", major factions, NPC registry
Characters	Character names, classes, brief concepts, and shared party bonds

Keeping this document up-to-date ensures everyone stays aligned on the campaign’s vision and avoids misunderstandings. It’s a simple but effective way to maintain clarity and consistency.

For longer campaigns, consider tools like World Anvil, Quill, or Chronicle RPG. These platforms can help track NPCs, plot threads, and session recaps effortlessly. As one GM, Marcus T., shared: "The AI session recaps alone saved me two hours a week. But what blew me away was when it flagged a plot thread I'd completely forgotten about - and my players thought I'd planned it all along". Remember, the GM doesn’t need to shoulder all the responsibility for campaign details. Collaborative tools can lighten the load and make the game more enjoyable for everyone.

Conclusion

From defining your campaign's main themes to setting up safety tools and scheduling guidelines, Session Zero builds the foundation for a successful campaign. It’s the moment where everyone aligns on expectations, ensuring smoother gameplay and fewer misunderstandings down the road.

"Session Zero is where a group negotiates the social contract of a campaign." - Tabletop RPG Authority

Research indicates that skipping this step is one of the strongest predictors of a campaign falling apart before its tenth session. A well-executed Session Zero, as described earlier, can save a campaign from future pitfalls.

Of course, every group is different. As Cameron Nichols, Senior Editor at D&D Fanatics, says: "Every table is different, and what works for your group may not work for another. So take what you need, adjust it to your group's style, and drop what doesn't work." For instance, a quick one-shot with friends might only require a 15-minute discussion, while a long-term homebrew campaign could need multiple sessions to iron out lore, mechanics, and expectations. The depth of your Session Zero depends on your group’s experience, preferred play style, and availability.

Once you’ve laid this groundwork, the next step is choosing a game system that fits your vision. If you’re still undecided, the TTRPG Games Directory is a fantastic resource. It offers an extensive list of classic and indie tabletop RPGs, complete with detailed breakdowns of mechanics, themes, and tone, to help you pick the perfect system before diving into your campaign.

FAQs

How long should Session Zero be?

Session Zero typically runs for 2–3 hours, though simpler setups might only need about 90 minutes. For quick one-shots, 15 minutes could do the trick, while intricate campaigns with custom-built worlds might require up to two full sessions. The length really hinges on the complexity of your campaign and what your players need. Tools like the TTRPG Games Directory can help you find games that align with your preferred style and structure.

What should I do if a player disagrees with the campaign tone or rules?

Session Zero is your chance to have an open and respectful conversation about the campaign's tone, rules, and expectations. If disagreements arise, this is the perfect time to address them. Work as a group to refine the campaign concept, tweak house rules, or resolve any concerns that might come up. The aim? To reach a shared understanding that makes the game fun for everyone involved.

It’s also a great opportunity to explore different tabletop RPG genres and mechanics to see what fits your group's preferences best. Whether you're diving into a gritty mystery or a lighthearted adventure, aligning on these details early can set the stage for an enjoyable experience.

How can I enforce safety tools like Lines and Veils without derailing play?

Starting with safety tools in Session Zero helps establish clear expectations from the get-go. To make this process easier and less intimidating, consider using anonymous questionnaires or consent checklists. These allow players to voice their boundaries without feeling pressured by the group dynamic.

Pair these static tools with a real-time option like the X-Card. This gives players the flexibility to address issues as they arise during gameplay. If someone signals a boundary has been crossed, immediately pause the game, offer a sincere apology, and adjust the situation - no explanations are required.

This proactive and respectful approach builds trust among players and ensures that safety tools feel like a natural part of the experience, rather than an interruption.
