Do You Need a Game Master? (Not Always)

Quick Answer: Not all TTRPGs require a Game Master. While classics like D&D 5e need a GM, many systems are designed for GM-less play or shared storytelling. Choose based on your group’s preference for structure versus collaboration.

Most tabletop RPGs require a Game Master (GM) to run the game, but not all. Some games are designed to be played without one, while others give you the choice. This guide explains the differences, lists examples, and helps you decide what’s right for your group.

What a Game Master Actually Does

A GM is the referee and storyteller of the game. They describe the world, control non-player characters (characters not controlled by players), and decide how the rules apply in unclear situations. For example, if players want to sneak into a castle, the GM describes the guards, the layout, and what happens if they’re caught. They also improvise when players do something unexpected, like negotiating with the guards instead of fighting them.

Being a GM requires preparation. They often read adventure modules (pre-written stories) or create their own worlds and plots. During play, they must balance challenge and fairness—making sure enemies aren’t too easy or impossibly hard. For beginners, this can feel overwhelming, especially if players go “off-script.” Games like Dungeons & Dragons rely heavily on the GM’s judgment, which is why many new players prefer simpler systems or GM-less alternatives.

However, a good GM makes the game come alive. They give players freedom while keeping the story moving. Without one, players must share these responsibilities—which works in some games but not others. The key is knowing whether your group wants that collaborative control or prefers a dedicated guide.

Games That Require a GM

These games expect one player to take the GM role, and removing them would break the game. Examples include Dungeons & Dragons, Call of Cthulhu, and The Sprawl. In D&D, the GM controls monsters, narrates exploration, and interprets dice rolls. In Call of Cthulhu, they portray mysterious cultists and decide how sanity-eroding horrors affect the players. The Sprawl, a cyberpunk game, relies on the GM to pressure players with corporate enemies and ticking clocks.

Why do these games need a GM? They’re built around hidden information. Players shouldn’t know the dungeon’s traps or the villain’s plans upfront—the GM reveals these gradually for suspense. They also handle complex rules that would slow down play if debated by the group. For instance, D&D combat involves tracking enemy health, spells, and positioning, which is smoother with one person managing it.

That said, GM-heavy games demand more work. The GM must prep maps, stats, and plot hooks before each session. New players often underestimate this. If your group wants to dive in quickly, consider a lighter system or a game where GM duties are shared.

Games Where the GM Is Optional

Some games let you play with or without a GM, depending on preference. Ironsworn is a great example. Designed for solo, co-op (no GM), or traditional GM-led play, it uses “moves” and “oracles” (random tables) to guide the story. If you play without a GM, the group collaborates on world-building and interprets oracle results together. For instance, rolling “danger” on an oracle might mean an ambush, but the players decide who attacks and why.

Another example is Beyond the Wall, which has a GM but gives players tools to help create the world. During character creation, they establish ties to the village and its threats, reducing the GM’s prep work. This shared approach works well for groups who want some structure but dislike one person bearing all the responsibility.

GM-optional games are ideal for players who want flexibility. They’re also good for rotating GMs—if one person burns out, the group can switch styles. However, they still require players to engage with rules and make fair judgments. If your group struggles with indecision, a traditional GM might be better.

Games With No GM at All

These games distribute GM tasks evenly among players. Fiasco, a comedy-of-errors RPG, has no GM. Instead, players take turns setting scenes and deciding outcomes. One might introduce a shady drug deal, then another escalates it into a police chase. The game’s structure (acts, tilts, and aftermath) keeps the story moving without a referee.

Similarly, For the Queen is a story game where players draw cards with prompts like “What did the Queen ask you to sacrifice?” and answer in character. The group collectively builds the Queen’s personality and the kingdom’s fate. There’s no GM because the game’s framework handles pacing and conflict.

GM-less games excel at short, focused stories. They’re perfect for one-shots (single-session games) or groups who dislike hierarchy. However, they require players to embrace improvisation and avoid “winning” mentality—since no one’s enforcing rules, conflicts must be resolved through discussion. Games like Ironsworn bridge the gap by offering structure without a GM.

Which to Choose Based on Your Group

For new players who want guidance: Pick a game with a GM. D&D or Call of Cthulhu provide clear roles—one person guides while others learn. Just make sure your GM is patient and willing to teach.

For small groups (2–3 players): Try GM-optional games like Ironsworn. They’re designed for intimate play and reduce the pressure of prepping a full campaign.

For improv-heavy groups: GM-less games like Fiasco or For the Queen work well if your friends enjoy collaborative storytelling over strict rules.

For rotating GMs or burnt-out GMs: Beyond the Wall or other GM-light systems let everyone contribute to world-building, preventing one person from shouldering all the work.

For solo players: Ironsworn is built for solo play, using oracles to simulate a GM’s decisions. It’s a great way to learn RPG mechanics without a group.

No option is “better”—it depends on your group’s preferences. If you’re unsure, start with a one-shot in each style to see what clicks.
