How Game Adaptations Differ from Their Source Material—and Why Changes Are Made

Game adaptations change because a story has to work in the medium receiving it. A television series can follow a fixed sequence and linger on characters; a game must also account for player action, gameplay, and level design. And when a game itself is being developed, its story may shift as the team works out how it should play. A change is not automatically a rejection of the source: its purpose depends on what changed and what the new version needs to do.

First, “game adaptation” can mean two different things

The phrase can describe a game being turned into a film or television series, or it can refer to changes made to a story while a game is being developed. The pressures differ. A screen adaptation reshapes material from an interactive work for a fixed, noninteractive narrative. Game development has to make narrative and play function together, sometimes while giving players meaningful control over events.

In either direction, adaptation is a set of choices: what to preserve, omit, expand, or reframe. There is no single method that fits every property. Asad Qizilbash, head of PlayStation Productions, makes that point in an interview with Sony Interactive Entertainment: “There’s not one size that fits all in terms of a method of adapting video games to film or TV.” The examples below illustrate particular creative decisions; they should not be mistaken for a universal industry formula.

Why a screen version may change a game’s story

A game and a screen story use different storytelling tools

A game can make progress depend on what a player does: exploring, overcoming challenges, or choosing how a character acts. A film or series presents a sequence selected by its creators. It can give a supporting character more room without asking the audience to play through that material, but it cannot make the viewer’s actions part of the plot in the same way a game can.

The Last of Us Part I – PlayStation 5

• Enhanced visuals: Completely rebuilt from the ground up using Naughty Dog’s latest PS5 engine technology to improve every visual detail, The Last of Us experience has been faithfully enhanced with more realistic lighting and atmosphere, more intricate environments and creative reimaginings of familiar spaces.
• Fast loading: Initial loading times are near instant, and seamless after the first instance thanks to the PS5 console’s SSD – so you can pick up where you left off in the story and load specific encounters and chapters more quickly.
• Haptic feedback: DualSense wireless controller haptic feedback support for every weapon elevates combat encounters, and environments are brought to life through DualSense wireless controller haptic sensations of subtle falling rain, the crunch of stepping on snow and more.
• Adaptive triggers: All The Last of Us iconic weapons, including Joel’s revolver and Ellie’s bow, now deliver dynamic DualSense wireless controller trigger resistance and kickback on firing for deeper combat immersion.
• 3D Audio: Designed to make use of the PS5 console’s Tempest 3D AudioTech, Naughty Dog’s newly upgraded audio engine delivers richer soundscapes, bigger explosive moments and more visceral gameplay through compatible stereo headphones (analogue or USB) or TV speakers.

That difference affects pacing and emphasis. Material that is compelling as a playable encounter may not have the same purpose when watched. Conversely, a scene or relationship that could not carry a game segment may become useful in a fixed narrative. Adaptation therefore is not simply a matter of transferring every event from one format to another. The screen version has to establish its own rhythm and make its story understandable without the original play experience.

The source may offer a story, a world, or a premise—not all three

Qizilbash contrasts The Last of Us, which has an established story, world, and characters, with Gran Turismo, whose games did not have an established story to adapt. Sony’s film about Gran Turismo instead centered on the true story of Jann Mardenborough, who played the game and became a professional race-car driver. The difference in starting material led to a different adaptation approach.

This comparison helps explain why “faithful adaptation” cannot mean the same thing for every game. A story-led source may give a screen production characters and narrative events to reinterpret. A game without an established plot may offer its identity, subject, or world as a starting point instead. Qizilbash describes the guiding idea for The Last of Us this way: “It’s all about using the source material as inspiration versus as a rule book.” That is one creator’s account of an adaptation philosophy, not a guarantee that every screen change serves the same purpose.

Some material can be expanded when it is no longer gameplay

Qizilbash cites deeper exploration of side characters in The Last of Us television adaptation as an example of material that could not work in a video game in the same way. A supporting character’s history or relationships can be given screen time without needing to become a playable objective. That does not make the original game deficient; it reflects a different use of narrative time.

Expansion also changes emphasis. When an adaptation gives more attention to one character or relationship, that choice can alter how viewers understand the larger story, even if the central premise remains recognizable. To assess such a change, identify what the screen version adds and what it displaces. “More detail” is not automatically better or worse; its effect depends on whether it serves the new work’s storytelling.

Why stories shift while a game is being made

Gameplay and narrative are developed together

For a game, narrative decisions have to coexist with the player’s moment-to-moment experience. A story beat may need to change if it conflicts with how a level works, what the player can do, or the pace of play. Ember Lab co-founder Josh Grier describes his team’s process as more iterative than film development. He says: “Gameplay is king and if you want to tell a compelling narrative within that, you have to be flexible.” He also describes the team working on creative solutions so gameplay and story can work together.

Grier is explaining Ember Lab’s approach, not stating a rule followed by every studio. The useful general point is narrower: in an interactive work, a narrative plan may be revised as the playable experience takes shape. A change can be a response to development rather than a judgment that the source story was wrong. The finished game has to make the story and the act of playing coherent together.

World and level design can shape what the plot can do

Nintendo’s interview with the developers of The Legend of Zelda: Echoes of Wisdom describes the team working through story and world decisions alongside gameplay. The developers discuss designing rifts that could appear in different locations, accommodate level design, and change as the story progressed. In this example, the placement and behavior of a story element were tied to the spaces players would encounter.

That relationship matters because a game’s world is not only a backdrop. Its layout affects what players can reach, when they learn information, and how a challenge unfolds. Plot and level design may therefore need to be adjusted together. The Nintendo interview documents choices for one game; it does not establish that every game handles world design or narrative in the same way.

Continuity is a creative constraint, not a simple checklist

In the same interview, Nintendo producer Eiji Aonuma discusses how much to add or change while keeping a game recognizably part of Zelda. The developers also consider how players may react when a plot seems inconsistent with other games in the series. A new installment can pursue a fresh idea, but a long-running series brings expectations about its world and history.

That can make continuity a balancing act. A story may need room for a new game’s mechanics and setting while still feeling connected to its series. A departure from established lore can be deliberate, but players may read it as a contradiction if the work does not make the relationship clear. The relevant question is not just whether a detail differs, but what the new story asks the player to understand about the series.

How player agency changes what a game story can be

Some games make the player’s decisions and their consequences part of the narrative itself. In a PlayStation.Blog interview, Will Byles, Supermassive’s executive creative director, described Until Dawn as a story that responds to what happens during play. He said, “The story will change, adapt.” He also explained that the player controls a character’s fate and that a character’s death advances the story rather than triggering a reset or respawn.

In this kind of design, a single fixed sequence is not the only possible account of events. Player actions help determine which outcomes occur. That changes the writer’s task: the narrative must account for consequences and continue after them. It can also mean that players encounter different versions of events, so a plot change is not necessarily a deviation from a single canonical path; it may be a response to the path a player created.

Byles also discussed minimizing on-screen interface elements in Until Dawn. He said the game was intended to be enjoyable both to play and to watch, and that fewer abstract interface elements helped preserve immersion. This is a presentation choice rather than a plot change, but it shows how the intended experience and audience context can influence a game’s form.

A practical way to judge an adaptation change

Before deciding whether a change is faithful, identify what changed and what the new work is trying to accomplish. These questions are a way to compare the examples—not a formal scorecard or a verdict that can be applied mechanically.

1. What is the source actually providing? Is it a developed plot and cast, a recognizable world, a gameplay premise, or a setting for a new story? The contrast between The Last of Us and Gran Turismo shows why that distinction matters.
2. What changed? Separate an omission from an addition, a reordered event, a new character emphasis, or a different player outcome. Naming the change prevents vague claims that an adaptation is simply “different.”
3. What does the new medium need? Ask whether the choice makes sense for a fixed screen narrative, or whether a game’s mechanics and level design require it. An explanation should connect the change to a concrete storytelling or gameplay function rather than assuming that every deviation has one.
4. Does the player’s action matter? In an interactive story, check whether choices change events or character outcomes. If they do, the story may be designed to branch or adapt rather than reproduce a single sequence.
5. How does the change relate to continuity? For a series, consider whether the new choice builds on, revises, or appears to conflict with what players already know. The response may depend on how the story frames that relationship.
6. What is the effect, not just the intention? A creator’s stated reason can explain a decision, but readers and players can still judge whether the finished work makes that decision clear and satisfying.

What creators’ explanations do—and do not—establish

The examples here come from interviews with people involved in the works discussed: Sony Interactive Entertainment’s interview with Qizilbash, Unreal Engine’s interview with Grier, the PlayStation.Blog interview with Byles, and Nintendo’s interview with the Echoes of Wisdom developers. They offer direct explanations of specific adaptation and development choices. They do not establish how often particular changes happen across the industry, or prove that one approach is universally best.

No named statistic in these accounts measures the frequency of changes or ranks their causes. It is more accurate to discuss the documented reasons—medium fit, gameplay, iteration, level design, continuity, audience expectations, and player agency—as examples, not as quantified industry-wide trends.

The central distinction

A source work is a starting point, but an adaptation also has to function as the kind of work it becomes. Screen versions can leave out game material or give different space to characters; games can revise narrative as play, level design, and player choice take shape. The strongest way to discuss any particular change is to name what was altered, explain the medium-specific problem or opportunity it addresses, and then judge how well the finished work uses that choice.
