Open Setting

Introduction

Open setting is a term used in the field of interactive narrative and game design to describe a type of game world that permits player-driven exploration, decision‑making, and narrative creation without the constraints of a tightly scripted plot. Unlike linear or story‑centric games, an open setting provides a framework of rules, geography, culture, and history that players can navigate freely. The concept has become central to many modern tabletop role‑playing games (RPGs), video games, and experiential learning environments.

Definition and Scope

The term “open setting” is often synonymous with “sandbox” in video‑game parlance, though the two are not identical. An open setting is characterized by an emphasis on player agency, emergent storytelling, and an underlying world that persists regardless of individual character actions. It typically includes the following attributes:

  • World Persistence – The setting continues to exist and evolve even when players are not actively participating.
  • Non‑Linear Exploration – Players can move in any direction and encounter events based on their choices.
  • Rule‑Based Consistency – While player actions may alter local conditions, the world adheres to a consistent set of rules that maintain coherence.
  • Optional Narrative – The setting may contain narrative hooks, but these are optional and can be ignored or subverted.
  • Multiple Entry Points – The world can be approached from various locations or storylines, accommodating diverse play styles.

Open settings contrast with campaign‑centric or guided‑play models, where a game master (GM) or narrative engine steers players through a pre‑planned storyline. In an open setting, the story emerges from player interactions with the world, often leading to unique outcomes that can be shared across groups.

History and Background

The roots of open setting can be traced back to early tabletop role‑playing games of the 1970s and 1980s. While the first RPGs, such as Dungeons & Dragons, were largely structured around pre‑written modules, designers soon experimented with more flexible frameworks.

Early Experiments (1970s–1980s)

In 1978, Gary Gygax and Dave Arneson released the first edition of Dungeons & Dragons. The game featured dungeon modules that guided players through predetermined quests. However, the concept of a larger world, exemplified by the setting of Greyhawk, began to emerge. Greyhawk was a sandbox in that players could create characters and explore the world outside the confines of any single module.

Simultaneously, the 1981 release of Traveller introduced a galaxy‑wide setting that encouraged interstellar exploration and trading. The game's rulebook emphasized world-building, giving players the tools to craft their own adventures within a persistent universe.

The Forgotten Realms Era (1990s)

The mid‑1990s saw the rise of the Forgotten Realms, a richly detailed fantasy world that became a standard setting for D&D adventures. Although many modules were still linear, the depth of lore allowed groups to branch off into side quests and spontaneous encounters. The setting's expansive history and geography provided a fertile ground for open‑ended gameplay.

During this period, the rise of computer role‑playing games further expanded the notion of open settings. Titles such as Ultima VI (1990) and Shannara (1991) pioneered non‑linear exploration, with players free to traverse vast landscapes, interact with NPCs, and pursue optional objectives.

Modern Open Worlds (2000s–Present)

The turn of the millennium brought major advances in technology and design philosophy, leading to the dominance of open‑world video games. Grand Theft Auto III (2001) and Red Dead Redemption (2004) offered players expansive cities and deserts to explore, with emergent stories arising from player behavior. The success of these titles cemented the open setting as a core mechanic in modern game design.

Tabletop RPGs also adopted open‑world concepts. World of Darkness introduced “the City” as an ever‑changing metropolis that could be explored at the discretion of the players. In 2010, Pathfinder released the Penn & Teller setting, a sandbox that encouraged player‑driven storytelling.

Recently, open settings have been applied to educational tools and experiential learning. Simulations such as Phantom VR use persistent environments to allow learners to experiment with complex systems over extended periods.

Key Concepts

Open settings are built upon several design principles that collectively empower player agency and emergent narrative. The following subsections delineate the core concepts that practitioners consider when creating or employing an open setting.

World Persistence and Realism

A persistent world maintains continuity independent of player actions. In tabletop RPGs, this means that locations, NPCs, and events are tracked by the GM, ensuring that a change made in one session can be reflected in the next. Video games implement persistence through save systems and state machines that record player choices and world changes.

Realism is not strictly about fidelity to the real world; rather, it concerns internal consistency. The rules governing physics, magic, economics, and politics must be logically coherent. When a player constructs a new trade route, the world’s economy should respond accordingly, creating tangible consequences.

Player Agency and Freedom of Choice

Player agency refers to the degree of control a player has over the narrative trajectory. In an open setting, players decide what to explore, whom to ally with, and what objectives to pursue. This freedom is typically facilitated by:

  • Comprehensive rulebooks that allow for improvisation.
  • A well‑structured geography that provides multiple paths to the same goal.
  • NPCs with autonomous motivations that respond to player actions.

Designers must balance freedom with coherence. Too much freedom can lead to narrative fragmentation, whereas too much structure can stifle creativity.

Emergent Narrative

Emergent narrative occurs when the story arises from the interaction of game mechanics rather than a pre‑written plot. This phenomenon is a hallmark of open settings. Examples include:

  • In tabletop sessions, a group may inadvertently stumble upon a hidden cult because of their curiosity, creating a new narrative thread.
  • In video games, the player’s choice to side with a particular faction can unlock entirely new story arcs.

Emergence relies on systems that interconnect. For instance, a quest that rewards the player with a unique item may unlock a new area, creating a loop of discovery.

Modular Design and Interoperability

Modular design allows components of an open setting to be reused across different scenarios. For tabletop RPGs, this might involve modular adventure hooks that can be inserted into a larger campaign. Video games use procedural generation to create varied terrain and events while maintaining a consistent underlying world model.

Interoperability refers to the ability of multiple game systems or modules to coexist within a single setting. For example, a tabletop group might play a horror module set in the same world as a fantasy module, with shared lore and NPCs.

Optional Narrative and Multiple Paths

Optional narrative means that storylines are not mandatory; players can choose to engage or ignore them. This concept is essential to prevent player fatigue and to allow for diverse play styles. Multiple paths ensure that there are several routes to achieving goals, thereby accommodating both linear and exploratory approaches.

Applications

Open settings are versatile and have been implemented across various domains. The following subsections explore their use in tabletop RPGs, video games, educational environments, and narrative design.

Tabletop Role‑Playing Games

Open settings have become a staple in modern tabletop RPGs. Designers often publish a world guide that provides lore, maps, and optional quests. Players and GMs can then create custom adventures that leverage this framework.

Notable tabletop open settings include:

  • Forgotten Realms – A high‑fantasy world with a vast library of lore available at Wizards.com.
  • Shadowrun – A cyberpunk setting that blends technology and magic, offering a modular world in shadowrun.com.
  • Eberron – A setting that blends magic with industrial innovation, accessible at dnd.wizards.com.

In each case, the setting provides a persistent backdrop that can be adapted to any style of play, from high‑level adventures to gritty urban exploration.

Video Games

Open worlds in video games range from sandbox experiences to narrative‑driven titles. Pioneering examples include:

  • Grand Theft Auto: San Andreas – An expansive city with a complex system of jobs, missions, and side activities, released by Rockstar Games.
  • Skyrim – An open world fantasy setting with an emergent quest system, published by Electronic Arts.
  • Red Dead Redemption 2 – Combines open exploration with a compelling narrative, developed by Rockstar Games.

Video game designers employ procedural generation, AI behavior trees, and persistent state systems to maintain an interactive environment that adapts to player actions. These technical approaches ensure that each playthrough can differ significantly from the last.

Educational and Training Simulations

Open settings are also used to teach complex systems in a hands‑on manner. Examples include:

  • Phantom VR – A virtual reality platform that simulates industrial environments for safety training.
  • National Geographic Education – Offers interactive world maps where students can explore geographic phenomena.
  • University research labs use open simulation environments to study emergent behavior in social systems, such as traffic flow or epidemic spread.

These applications rely on the same principles of persistence, agency, and emergent narrative to create realistic and engaging learning experiences.

Narrative Design and Writing

Open settings are increasingly used in interactive fiction and branching narrative design. Writers create a world framework that allows readers or players to choose paths, thereby generating unique storylines. The Choose Your Own Adventure books from the 1980s exemplified this approach, and modern digital platforms like Ink provide tools to build such stories.

Game designers use open settings to create immersive storylines that respond to player choices. By embedding multiple sub‑plots and dynamic NPCs, they craft worlds where every action can have a ripple effect on the narrative fabric.
