OSR vs NSR: 7 Differences Every Game Master Should Know

OSR (Old School Renaissance) and NSR (New School Revolution) are two popular RPG styles with distinct approaches. Here’s a quick breakdown of their differences:

• OSR focuses on simplicity, GM rulings, player problem-solving, high-risk combat, and survival-based progression in classic fantasy worlds.
• NSR emphasizes streamlined rules, collaborative storytelling, narrative-driven conflicts, and character growth through story milestones in imaginative settings.

Quick Comparison

Whether you prefer OSR's high-stakes challenges or NSR's narrative freedom, the best choice depends on your group's play style. Keep reading for a detailed breakdown of these two RPG philosophies.

Basic Principles

OSR: Classic RPG Style

OSR, or Old School Revival, brings back the feel of early tabletop RPGs, focusing on simplicity and encouraging players to think creatively rather than relying on dense rulebooks. In these games, the Game Master (GM) has the freedom to make on-the-spot decisions, creating a dynamic and unpredictable experience where players' cleverness often determines success.

Here are the core elements that define OSR gameplay:

While OSR thrives on simplicity and player ingenuity, NSR takes these principles and evolves them with modern game design.

NSR: Modern Game Design

NSR, or New School Revolution, builds on OSR's foundation but incorporates modern mechanics and a stronger emphasis on collaborative storytelling. Where OSR leans on the GM's quick decision-making, NSR introduces clearer rules and encourages shared narrative creation.

Key features of NSR include:

• Streamlined, consistent rules that keep the game flowing and support storytelling.
• Innovative settings that break away from traditional fantasy tropes, offering fresh worlds to explore.
• Collaborative storytelling, where both players and the GM contribute to shaping the narrative.

This approach shifts the focus from survival and resource management - hallmarks of OSR - to creativity and narrative risk-taking. While OSR challenges players with high-stakes encounters and limited resources, NSR invites them to build imaginative worlds and take bold storytelling chances.

In OSR, the GM's interpretation of rules is the driving force behind gameplay decisions. NSR, on the other hand, strikes a balance by blending GM control with player input, creating a more cooperative and story-driven gaming experience while keeping mechanics simple and accessible.

Rules and Flexibility

OSR: Simple Rules, Strong GM

OSR (Old School Renaissance) games are built around the idea of keeping rules minimal and giving the Game Master (GM) significant authority. Matthew Finch, the creator of OSRIC, captures this philosophy perfectly:

"Rulings Not Rules: Gameplay decisions should be based entirely on the DMs interpretation of the rules, rather than focusing on the rules themselves".

Here’s how some popular OSR games reflect this principle:

This system gives GMs the freedom to make quick decisions, adapt to the group's style, and focus on the story rather than being bogged down by strict rules.

NSR: Clear Rules, Easy Play

NSR (New School Revolution) games take a different path, refining and simplifying rule systems to make gameplay more accessible and fluid. Games like Cairn, Mothership, and MÖRK BORG illustrate this approach by emphasizing clarity and ease of use.

Key characteristics of the NSR design philosophy include:

• Streamlined Core Rules
  These games trim unnecessary complexity, allowing the narrative to flow without interruptions.
• Balanced Authority
  NSR games provide structured frameworks that guide GMs, making them especially helpful for newer game masters.
• Modern Design
  Titles like Troika and Knave introduce innovative mechanics that keep gameplay engaging while maintaining simplicity.

This mix of structure and creativity makes NSR games approachable for newcomers while still fostering dynamic, collaborative storytelling.

Player Choice and Story Control

Player choice is a cornerstone of gaming, shaping experiences in profound ways. When it comes to OSR (Old School Renaissance) and NSR (New School Revolution), these two styles offer distinct takes on decision-making and narrative control.

OSR: Player Problem-Solving

In OSR games, the spotlight is firmly on the players' creativity and problem-solving skills, rather than relying on character stats. As Matthew Finch explains:

"Player skill is more important than character abilities. Outwit the enemy, don't simply out-fight them".

Here’s how OSR keeps players engaged:

These elements ensure that the narrative evolves directly from the players' actions and decisions, creating a dynamic and often unpredictable story.

NSR: Group Storytelling

NSR games, while retaining some OSR values, lean heavily into collaborative storytelling. The focus shifts to emergent narratives, where the story grows organically from player interactions and decisions. In NSR, choices shape both the mechanics and the unfolding tale.

Burtonja captures this philosophy well:

"NSR Games typically have: a GM in control of the game overall, a 'non-vanilla' setting, are rules lite and focus on emergent narrative and exploration".

This approach invites players into a shared creative process, where their decisions not only impact the mechanics but also weave together a rich, evolving story.

Combat and Risk

Combat and risk are central to both OSR and NSR gaming styles, but they approach these elements in very different ways.

OSR: High-Risk Combat

In OSR games, combat is inherently dangerous, making careful planning and strategy essential. Players are encouraged to think twice before engaging in direct confrontations.

"Higher lethality means that people in general won't just kick down the door and assume that they'll likely triumph against whatever is on the other side... High lethality does mean that more planning, intel and strategy is required."

In OSR, every combat decision carries weight, and mistakes can have lasting consequences. This forces Game Masters (GMs) to design encounters with precision, ensuring they challenge players without feeling unfair. The focus is on survival and problem-solving over brute force.

NSR: Story-Based Conflict

NSR games take a different approach, focusing on advancing the narrative rather than emphasizing danger or tactical precision. Conflict becomes a tool for storytelling, not just a test of strategy.

Some defining traits of NSR include:

• Fast character creation, so players can jump into the story quickly.
• Conflict that drives the narrative, rather than focusing solely on mechanics.
• Options for non-violent resolutions, allowing players to solve problems in creative ways.

A great example of this is The Black Hack system. In this game, characters with less than 5 HP often play cautiously, leading to fewer combat encounters and no character deaths compared to more traditional systems. This system shifts the focus from tactical survival to meaningful story progression.

"Having meaningful consequences makes decisions really matter... If we want the feeling of danger and high stakes, sometimes that has to deliver. And if we're not going to abide by the results of the dice, we shouldn't be rolling them in the first place."

Character Growth

OSR: Survival-Based Progress

In OSR games, character growth is closely tied to survival and the accumulation of resources, with progress measured through tangible, numerical improvements. This system rewards players for their strategic actions and achievements, creating a clear and structured path for advancement.

One standout example is the Adventurer Conqueror King System (ACKS), which awards experience points for various activities such as gathering treasure, defeating monsters, building strongholds, engaging in trade, and conducting magical research. These mechanics give players a clear roadmap for progression, rewarding calculated risk-taking and resource management.

On the other hand, NSR games take a very different approach, prioritizing character growth through storytelling and in-world developments.

NSR: Story-Driven Development

NSR games shift the focus from numbers to narrative, embedding character growth into the story itself. Instead of abstract level-ups, characters improve through meaningful in-world achievements and choices, creating a more organic sense of development.

Key elements of NSR character growth include:

• Diegetic Advancement: Characters evolve through in-world milestones, such as gaining influence or acquiring unique abilities.
• Story Milestones: Progression is tied to narrative accomplishments rather than numerical thresholds.
• Flexible Growth: Character development adapts to decisions and story direction, allowing for more personalized arcs.

For instance, in Call of Cthulhu, characters maintain their professional skills throughout the game, with growth manifesting through story-driven developments rather than major statistical changes. This mirrors how learning and growth occur in real life - gradually and contextually.

Some NSR games also introduce mechanics like "failing upwards", where surviving dangerous or dramatic situations leads to character growth. This approach ties development directly to the story’s tension and drama, making progress feel earned and deeply connected to the narrative.

Game Worlds

OSR: Standard Fantasy

OSR game worlds stick closely to the roots of medieval fantasy, creating a setting that feels both timeless and familiar. These settings lean heavily on classic tropes, offering a backdrop that players and GMs can easily recognize and engage with. Here's a quick breakdown of the key elements often found in OSR settings:

In OSR games, the emphasis on dungeons and wilderness environments reinforces the thrill of exploration and the challenge of survival. These worlds are designed to support classic adventure themes, allowing GMs to build scenarios that test players within a recognizable framework. While OSR thrives on this traditional approach, NSR takes a different route by pushing boundaries and rethinking conventions.

NSR: New World Types

NSR games, on the other hand, break away from the mold, introducing imaginative and often surreal worlds that prioritize storytelling and player-driven narratives. Instead of relying on detailed lore, these settings focus on distinctive character backgrounds and dynamic interactions, leaving room for players to shape the story as it unfolds.

Take Mörk Borg, for example. This NSR title embraces a grim, heavy metal-inspired aesthetic paired with a straightforward ruleset. Its world is chaotic and brutal, with ongoing background events that evolve independently of player choices. This approach flips traditional fantasy and sci-fi tropes on their heads, offering something fresh and unpredictable.

NSR settings often pull inspiration from a variety of sources, blending elements like Greek mythology, modern music, and other eclectic influences. This mix empowers GMs to create worlds that feel rich and layered, while still leaving ample room for emergent storytelling and player creativity. These worlds aren't just settings - they're active, evolving landscapes that challenge both players and their expectations.

GM Responsibilities

OSR: Fair Judge

In OSR games, GMs take on the role of neutral referees. Their job is to ensure fair and consistent rulings while maintaining balance in the game. Decisions are made using straightforward frameworks, allowing the game to flow naturally.

Instead of following a rigid storyline, OSR GMs focus on creating dynamic situations that let players shape the narrative. Game Designer Sean Foer from StartPlaying explains this approach perfectly:

"The OSR harnesses the power of emergent narrative and discourages preordained outcomes from GMs. Rather, the GM presents the situation, the players take action, and the dice fall where they may, producing a story that evolves naturally and directly through play".

NSR: Story Partner

NSR games take a different approach, redefining the GM's role as a collaborative storyteller. Here, the GM works closely with players to create engaging narratives, offering support and crafting challenges that enrich the story. This style emphasizes:

• Facilitating narratives that evolve through gameplay
• Designing imaginative, non-traditional settings
• Encouraging player-driven storytelling
• Adjusting the story based on group input

In this role, the GM becomes the players' biggest advocate. As hildissent puts it:

"Be a fan of the PCs, make the world feel real, upset the status quo, etc."

Whether in OSR or NSR, a GM's creativity and attentiveness remain critical. Mars_Alter captures the essence of the role:

"Design the world, describe it to players, roleplay the NPCs, and fairly adjudicate uncertainty in action resolution".

In short, OSR GMs act as impartial judges, while NSR GMs collaborate with players to co-create a shared story. Both styles require a careful balance of fairness, creativity, and adaptability.

Conclusion: Picking Your Style

Deciding between OSR and NSR isn't about determining which system is "better." It's about finding what resonates with your group's preferences and play style. Each approach offers its own flavor and strengths, shaping how your tabletop adventures unfold.

Here's a quick breakdown of how these systems differ:

James Raggi sums it up perfectly when discussing the potential of blending these two styles:

"Carcosa was, in my eyes, the first project demonstrating that the Old School Renaissance didn't have to be about preserving and fetishizing the past - it could be about building something new and daring without losing the old school ethos or the old school rules. The best of both worlds."

When deciding which system to embrace, consider these points:

• Go with OSR if your group enjoys creative problem-solving and thrives on high-stakes challenges. Its structured mechanics and clear progression paths cater to those who love traditional gameplay.
• Opt for NSR if collaborative storytelling and character-driven narratives are your focus. Its rules-light approach and imaginative settings allow for greater narrative freedom.

Ultimately, your choice reflects your group's play style and storytelling ambitions. Both systems highlight the evolving nature of tabletop RPGs, offering endless opportunities to craft memorable adventures.
