The History of Video Games: From Pong to Open Worlds

In 1986, a Japanese cartridge told players almost nothing about where to go. The Legend of Zelda dropped you into a forest with a sword, an old man's cryptic advice, and a map you had to fill in yourself. In 2022, Elden Ring gave players a horse, a fractured kingdom, and an estimated 79 square kilometres (30.5 square miles) of terrain to interpret, according to independent measurement analysis cited by Screen Rant. Both games share a design lineage that most histories of gaming skip over: the specific, traceable evolution of the open world as a genre, not just a feature.
This is not a business history of consoles and sales charts. It's the story of a design idea — give the player a world and let them decide what to do in it — and how that idea moved from a single non-linear NES cartridge to the dominant, sometimes exhausting, format of modern gaming.
What "open world" actually means, and why it's harder than it sounds
"Open world" gets used loosely to describe almost any game with more than one path through it, but the term has a more specific design meaning. An open-world game gives the player a persistent, explorable space they can move through with meaningful freedom, where the order of activities is largely up to them rather than fixed by the designer. That's different from a game with multiple levels, or even a game with branching paths, because the world itself has to hold together as a continuous, navigable place rather than a sequence of discrete rooms.
Building that kind of space creates problems linear game design never has to solve. A linear game can control exactly what the player sees, in what order, and can hide its seams behind loading screens and scripted sequences. An open world has to make the player feel free while still guiding them toward the content the designers actually built, and it has to do that without the game collapsing into either an empty, aimless field or an over-signposted checklist. Every open-world game in this history is, in some sense, a different answer to that same design tension.
There's also a hardware problem baked into the genre's history. Rendering, storing, and streaming a large continuous space taxed every generation of hardware it touched, from the NES's tiny cartridge memory to the PlayStation 2's limited RAM to the current generation's need to stream high-resolution assets in real time as a player runs across a map. The genre's technical history and its design history are inseparable — an open world could not get bigger, denser, or more reactive until the hardware underneath it caught up.
Zelda's overworld: the first open map on a console
The Legend of Zelda, released in Japan in 1986 and in North America in 1987, is the point most design historians trace the modern open-world lineage back to. Its overworld was a grid of connected screens that the player could enter from almost any direction, and the game gave almost no explicit instruction about which dungeon to tackle first. That structural choice — allowing different areas of Hyrule to be explored in any order without a rigid sequence of events — was, by most accounts, a first for a console game, and it directly shaped how the rest of the action-adventure genre would be built for decades afterward.
What made this work as a design, rather than just a confusing mess, was information design rather than raw freedom. Zelda scattered visual clues — a suspicious rock formation, a burnable bush, a lake that seemed to lead nowhere — that rewarded attentive exploration without ever explicitly telling the player "go here next." Game designer analyses of the original Zelda's level design, including retrospectives published by Game Developer, describe this as an early masterclass in teaching a player to read a world's geography as a puzzle, rather than following a marker.
This is the first of two ideas worth holding onto through the rest of this history: an open world isn't just "a big space," it's a space with enough embedded information that players can navigate it without being told where to go. Zelda solved that problem with hand-placed environmental hints on a scale small enough that a single designer could plausibly track every screen. That approach would not scale to what came next.
How did The Legend of Zelda influence open-world game design?
Zelda (1986) established that a console game could let players explore in any order and still feel coherent, using environmental clues instead of forced linearity. That non-linear structure, largely abandoned by more guided later entries in the series, became the direct design reference point Nintendo returned to when building Breath of the Wild three decades later.
GTA III: from a hand-crafted overworld to a simulated city
Fifteen years after Zelda's overworld, Rockstar Games released Grand Theft Auto III in October 2001 for the PlayStation 2, and it solved a completely different version of the open-world problem. Where Zelda's Hyrule was a fixed grid of hand-designed screens, GTA III's Liberty City was a continuous three-dimensional space the player could drive, walk, or shoot their way through in real time, with traffic, pedestrians, and a functioning economy of side activities layered on top of a main story.
The technical trick that made this possible was level streaming: the game loaded and unloaded parts of the city dynamically as the player moved through it, rather than requiring the whole map to sit in memory at once. That single engineering decision, described in technical retrospectives of the game's architecture published by outlets covering its 2001 development, let a PlayStation 2 with severe memory constraints simulate a whole living city instead of a series of separate loading-screen zones. It is the direct ancestor of the streaming techniques every large open world since has depended on, from Los Santos to Night City to the Lands Between.
GTA III's real innovation, though, wasn't the city itself, it was what the city was for. Zelda's overworld connected discrete, designed encounters — a dungeon here, a hidden cave there. GTA III's Liberty City was designed to be inhabited, not just traversed: you could ignore the story entirely and just cause chaos, steal cars, or wander, and the game world would react to you in the moment rather than waiting for you to trigger the next scripted event. Rolling Stone's retrospective on the game's 15th anniversary called it the blueprint the entire open-world genre built on afterward, and that's a fair description — nearly every open-world game released in the following decade, from Just Cause to Saints Row to Assassin's Creed, borrowed some version of GTA III's "living city with a story layered on top" structure, as documented by Rolling Stone.
What made GTA III different from earlier open-world games?
GTA III combined a continuous, streamed three-dimensional city with systemic behavior — traffic, pedestrians, and reactive chaos — rather than a series of discrete hand-designed screens. That shift, from a world built around fixed encounters to a world built to be simulated and inhabited, became the template most subsequent open-world games followed.
Skyrim and The Witcher 3: two answers to "what fills the world"
By the early 2010s, the technical problem of building a large continuous world was mostly solved. The harder problem the genre turned to was content: once you've built a map that size, what do you actually put in it, and how much of it can realistically be hand-authored?
Bethesda's answer, refined across The Elder Scrolls V: Skyrim (2011), was procedural quest generation. Skyrim's Radiant system is a quest generator that assembles missions from interchangeable components — a location, an enemy type, a reward — with some elements randomized each time the quest triggers, according to design breakdowns published by the Unofficial Elder Scrolls Pages. A Radiant fetch quest can send you to a randomized bandit camp you've never visited, then send a different player to a different one entirely. The system can't produce a complex, narratively rich quest, but it can produce a functionally infinite number of simple ones at a fraction of the cost of hand-building each one, which lets a world of Skyrim's size stay populated with things to do almost indefinitely.
CD Projekt Red took the opposite approach with The Witcher 3: Wild Hunt (2015). There is no quest generator; every contract, side story, and main quest was hand-written, with a finite amount of content and a defined ending. That's a genuine trade-off, not just a stylistic preference: The Witcher 3's world is smaller in raw activity count than Skyrim's, but its individual quests carry narrative weight and moral complexity that a Radiant-style generator structurally cannot produce, because a generator has no way to write a genuinely surprising twist into a randomized fetch quest.
Neither approach is simply "better" — they're answers to the same underlying design question that trace back to Zelda's original problem of filling a map with meaningful content, scaled up to a world orders of magnitude larger than Hyrule's. Skyrim optimized for a world that never runs dry; The Witcher 3 optimized for a world where nearly everything you find was deliberately placed by a writer.
Table: How four landmark open worlds solved the same core design problem
| Game (year) | World-filling approach | Core innovation | Main design trade-off |
|---|---|---|---|
| The Legend of Zelda (1986) | Hand-placed screens with environmental clues | First non-linear console overworld | Small scale, limited by cartridge memory |
| Grand Theft Auto III (2001) | Continuous streamed 3D city, systemic behavior | Level-streaming enabled a "living" world | Content density thinner than a hand-built map |
| Skyrim (2011) | Procedural Radiant quest generation | Effectively infinite repeatable content | Generated quests lack narrative depth |
| The Witcher 3 (2015) | Fully hand-authored, finite quest content | Narrative depth in nearly every side quest | World runs out of new content once finished |
Breath of the Wild: bringing Zelda's original idea back, with physics
Where Skyrim and The Witcher 3 mostly debated how to fill a world, The Legend of Zelda: Breath of the Wild (2017) went back to the genre's original question — how much can you not tell the player, and still have it work — and answered it with a physics-driven system Nintendo calls the Chemistry Engine. The Chemistry Engine tracks how objects change each other's states rather than just how they move: burning grass creates an updraft that extends how far a player can glide, cutting down a tree lets it roll into water and become a raft, and carrying metal equipment during a thunderstorm turns the player into a lightning rod, according to reporting on the system by GamesBeat.
That system matters for this history because it's a direct technological descendant of the same design goal Zelda pursued in 1986: let the player figure things out rather than telling them. Nintendo's own stated design philosophy for Breath of the Wild, echoed across multiple design retrospectives including The Ringer's, was to build a set of simple, consistent physical rules that combine into complex situations, so that players feel clever for discovering a solution rather than following a marker toward one. That's Zelda's 1986 overworld logic, rebuilt with 2017 hardware: instead of hand-placed environmental hints on a grid of screens, the rules themselves generate the hints, everywhere, all the time.
The result was widely treated as a genre reset. Breath of the Wild deliberately abandoned the quest-marker-heavy, checklist-driven open-world formula that Ubisoft-style games (Assassin's Creed, Far Cry) had made into an industry default by the mid-2010s, replacing icon-hunting with a world you were meant to read and interpret, much closer in spirit to the unmarked Hyrule of 1986 than to the map-icon-saturated open worlds that dominated the genre in between.
How did Breath of the Wild change open-world game design?
Breath of the Wild replaced quest-marker-driven exploration with a physics and "chemistry" system where simple, consistent rules (fire creates updrafts, metal attracts lightning) combine into emergent solutions the player discovers rather than follows. It deliberately returned to the non-linear, minimally guided exploration philosophy of the original 1986 Zelda after years of more marker-heavy entries in the series and genre.
Elden Ring: legacy dungeons inside an open world
FromSoftware's Elden Ring (2022) took a hybrid approach that borrows from nearly every prior generation of open-world design discussed so far. Its overworld, independently measured by players and fan analysis at roughly 79 square kilometres (30.5 square miles), with an accessible traversable area closer to 40 square kilometres according to figures compiled by Games Learning Society, functions as connective tissue between what the game calls "legacy dungeons" — dense, hand-authored, Dark Souls-style linear areas dropped into an otherwise open map.
This is, in effect, a synthesis of Zelda's hand-placed screens and GTA III's continuous streamed world: the overworld gives players GTA III-style freedom to approach content in almost any order and to ignore most of it if they choose, while the legacy dungeons preserve the tightly authored, hand-built density that FromSoftware's earlier, fully linear Dark Souls games were known for. Underground areas like Siofra River and Ainsel River add further explorable space layered beneath the surface map, extending the total accessible area without extending the map's visible footprint at all.
Elden Ring also inherited Breath of the Wild's minimal-guidance philosophy more than it inherited the map-icon approach of mid-2010s open worlds: there's no quest log, few explicit markers, and progression is driven largely by the same kind of environmental reading the original Zelda taught players to do in 1986 — noticing a distant structure, following a faint path, guessing what a landmark implies about what's inside it.
The open-world fatigue debate
By the mid-2020s, the genre's own success had become its biggest design problem. Ubisoft's Assassin's Creed Odyssey (2018) was widely criticized for being oversized relative to its content density, and the studio's public response — building the smaller, more contained Assassin's Creed Mirage — was a direct acknowledgment that bigger maps weren't automatically better games, a shift discussed in retrospectives including one published on Medium. The broader industry discourse around 2023 crystallized into a specific complaint sometimes nicknamed "yellow paint" criticism — the practice of literally painting climbable surfaces and interactive objects yellow so players can navigate an open world without having to read it, the exact opposite of what Zelda's environmental clues and Breath of the Wild's chemistry system were designed to teach players to do, a tension examined by CBR.
The core of the fatigue argument isn't that open worlds are bad, it's that scale and content volume had, for a stretch of the genre's history, become a substitute for the actual design problem this entire history has been about: giving players a space that rewards attention rather than one that simply takes longer to walk across. A 79-square-kilometre Elden Ring, dense with legacy dungeons and unmarked secrets, and a 100-plus-hour open-world game padded with repetitive collectible icons, can have similar map sizes and completely different design quality, because size was never the variable that mattered. Zelda proved that with a handful of connected NES screens in 1986; the industry spent the following decades occasionally forgetting it, before Breath of the Wild and Elden Ring both, in different ways, relearned it.
What people get wrong about open-world history
The most common misconception is that open-world design is a recent phenomenon tied to 3D graphics and powerful hardware, when the design idea itself — freedom of order, environmental storytelling instead of forced sequence — predates 3D graphics by fifteen years and was solved, in a limited form, on hardware with a tiny fraction of a modern console's memory. GTA III didn't invent the open world, it solved the specific engineering problem of rendering one continuously in three dimensions.
A second common error is treating "bigger" as a straightforward measure of design progress across this history. Elden Ring's 79 square kilometres are not simply "better" than Zelda's grid of NES screens or The Witcher 3's more contained Velen and Novigrad; they're differently structured. The design lineage traced here isn't a story of maps getting larger, it's a story of the same problem — how much freedom to give a player, and how much information to embed in the world instead of a menu — being solved in fundamentally different ways as hardware, and player expectations, changed.
A third misconception is that procedural systems and hand-authored content are competing philosophies, with one destined to win. Skyrim's Radiant quests and The Witcher 3's fully scripted content aren't rival approaches heading toward a single correct answer, they're a genuine trade-off between infinite, shallow content and finite, deep content, and most modern open-world games, including Elden Ring's blend of open exploration and legacy dungeons, borrow pieces of both rather than picking a side.
FAQ
Q: Which game is considered the first open-world video game? A: The Legend of Zelda (1986) is widely credited as the first console game with a genuinely non-linear open world, letting players explore its overworld in almost any order. Earlier computer games experimented with open exploration, but Zelda established the template that shaped the console genre.
Q: What made Grand Theft Auto III different from earlier open-world games? A: GTA III (2001) combined a continuous, level-streamed three-dimensional city with systemic behavior like traffic and reactive pedestrians, rather than a series of discrete hand-designed screens. That "living city" structure became the blueprint most open-world games followed for the next two decades.
Q: How does Skyrim's Radiant quest system work? A: Skyrim's Radiant system generates quests by combining interchangeable components — a location, an enemy type, a reward — with some elements randomized each time, producing a near-infinite number of simple, repeatable missions rather than a fixed set of hand-written ones.
Q: What is Breath of the Wild's Chemistry Engine? A: It's a system that tracks how objects in the game world change each other's states, not just how they move — for example, burning grass creates updrafts, and metal equipment attracts lightning in storms. It lets simple, consistent rules combine into complex, player-discovered solutions across the whole map.
Q: How big is Elden Ring's open world? A: Independent measurement and fan analysis, since FromSoftware hasn't published an official figure, puts Elden Ring's overworld at roughly 79 square kilometres (30.5 square miles), with an accessible traversable area closer to 40 square kilometres once inaccessible terrain is excluded.
Q: What is "open-world fatigue"? A: It's industry and player criticism, prominent from around 2018 onward, of open-world games that prioritize map size and activity count over content quality, often relying on repetitive collectible icons or literal "yellow paint" markers to guide players through under-designed spaces rather than rewarding genuine exploration.
Q: Is a bigger open world always a better one? A: No. Design retrospectives and player criticism consistently show that content density and how much a world rewards attentive exploration matter more than raw map size — Elden Ring's dense, hand-placed secrets and The Legend of Zelda's small 1986 overworld are both considered stronger designs than several much larger, thinner open worlds released between them.
Q: What's the difference between Skyrim's and The Witcher 3's approach to open-world content? A: Skyrim (2011) uses procedural quest generation to keep its world populated with effectively infinite simple content, while The Witcher 3 (2015) relies entirely on hand-authored, finite quests with deeper narrative complexity. Neither approach is objectively superior — they represent different trade-offs between quantity and depth.
The takeaway
The history of open-world game design isn't a straight line from small to large, it's a repeated argument with the same question: how much of the world should the designer explain, and how much should the player be left to figure out. The Legend of Zelda answered that question in 1986 with a handful of NES screens and environmental hints; Grand Theft Auto III answered it in 2001 by making the world itself feel alive; Skyrim and The Witcher 3 gave opposite answers about whether that world's content should be generated or hand-written; and Breath of the Wild and Elden Ring both, in their own ways, circled back to Zelda's original instinct that a world which trusts the player to read it beats one that simply tells them where to go. The open-world fatigue debates of the 2020s aren't a rejection of that lineage, they're a reminder of the lesson every landmark game in it already taught: scale was never the point.
