Best eBooks That Became Video Games: Stories That Leapt Off the Page

Discover the best eBooks that became video games — The Witcher, Metro 2033, Parasite Eve, S.T.A.L.K.E.R. and more — plus what book-to-game crossovers mean...

Some stories are too big for a single medium. A reader closes the last page, and the world keeps breathing — until a game studio picks it up and asks the dangerous question: what if you could live inside this? The catalogue of books that became video games is far shorter than the list of books that became films, and that scarcity is exactly what makes each success worth studying. Every adaptation on this list solved the hardest problem in crossover storytelling: converting a world you follow into a world you control.

At EBOKIO — a UK-based digital publishing platform and ebook marketplace that connects independent authors and publishers with readers across the world — we watch these crossovers closely. They prove that an ebook is never just a file. It is an intellectual property with a future. Below, we walk through the finest examples, from Warsaw to the Moscow Metro, and end with what all of this means for the authors and readers building the next generation of digital publishing on platforms like ours.

Why Books Make Such Strong Source Material for Games

A novel arrives complete. The geography is mapped, the politics explained, the character arcs tested against thousands of reader hours before a single developer touches the license. A game studio buying a book isn’t buying a plot — it’s buying a world that already survived an audience. That de-risks the single most expensive decision in game production: choosing what to build.

There is a second advantage that film cannot match. Books are written in the conditional tense of the imagination; games run on conditions. A novel that describes a moral grey zone, a deadly ecosystem, or a branching consequence is already speaking the native language of game design. The best adaptations below understood this. They did not transcribe their sources — they translated them into systems, choices, and consequences the reader can now push against.

1. The Witcher — Andrzej Sapkowski’s Monster-Hunting Saga

The Witcher began almost by accident. In 1986, a Polish travelling salesman named Andrzej Sapkowski entered a short-story contest run by the magazine Fantastyka with a piece called ‘Wiedźmin’ — a wry twist on European fairy tales in which a professional monster hunter, Geralt of Rivia, is the working man and the monsters are often the sympathetic party. The story placed third. The character refused to disappear, and Sapkowski spent the following decades expanding it into a saga of story collections and novels.

The games arrived when Warsaw-based CD Projekt Red licensed the property and made a decision that still looks brilliant: they would not retell the books. The trilogy — The Witcher (2007), Assassins of Kings (2011), and Wild Hunt (2015) — functions as a non-canonical continuation, beginning after the novels end. Sapkowski kept his ending; the studio kept its freedom. The result earned Metacritic scores of 81, 88, and 93, and the series passed 75 million copies sold by March 2023, with The Witcher 3: Wild Hunt alone responsible for over 50 million — figures that place it among the best-selling game franchises ever made.

The books gained enormously in return: translated into 37 languages with more than 15 million copies sold, and when Netflix released its series in late 2019, Sapkowski’s book revenue jumped by a reported 562 percent within two weeks. One telling data point: the overwhelming majority of The Witcher 3’s profit came from outside Poland — the games acted as the books’ global marketing department. If you love morally tangled fantasy like this, browse our curated fantasy shelves in the EBOKIO store ( https://ebokio.com/ ) — several of our independent authors cite Sapkowski’s short-fiction origins as proof that a single strong character can carry an entire universe.

2. Metro 2033 — Dmitry Glukhovsky’s Underground Odyssey

Metro 2033 has the most unusual birth story on this list. In 2002, Russian journalist Dmitry Glukhovsky posted his post-apocalyptic novel online, chapter by chapter, entirely free, and let an audience grow around it before print houses showed interest. The premise — survivors of nuclear war living in the Moscow Metro, where each station is a tiny state with its own ideology — spread by word of mouth until the book was published on paper in 2005, with an English edition arriving in 2010 to coincide with the game.

When rights offers came, Glukhovsky chose a video game adaptation over a film, later explaining that games granted him more artistic freedom. Kyiv-based 4A Games delivered Metro 2033 in 2010, a first-person shooter where bullets double as currency and a gas mask filter is a countdown clock. Glukhovsky returned as scriptwriter for Metro: Last Light (2013); Metro Exodus (2019) opened the tunnels into Russia’s surface wilderness, and the VR exclusive Metro Awakening (2024) extended the lineage again.

Glukhovsky did something even more interesting for authors watching from the sidelines: he opened his world to other writers. The ‘Universe of Metro 2033’ project published dozens of novels by different authors inside his setting. That is franchise thinking applied to literature — a lesson every independent author on EBOKIO can study. A world readers return to is worth more than a book they finish once.

3. Parasite Eve — Hideaki Sena’s Biological Horror

Hideaki Sena holds a doctorate in pharmacology, and it shows. His 1995 novel Parasite Eve turns mitochondria — the energy-producing structures inside every human cell — into sentient antagonists plotting to overthrow their hosts. It won the first Japan Horror Novel Award and became a landmark of Japanese science horror. When Square adapted it for the original PlayStation in 1998, the studio again chose continuation over imitation: the game is a sequel, relocating the mitochondrial uprising to New York City and following rookie NYPD officer Aya Brea through a collapsing Christmas Eve.

Parasite Eve demonstrated that a book-to-game adaptation could honor its source while speaking to a completely different audience. The novel reads like a medical thriller; the game plays like a survival RPG with opera-house set pieces. Both work because Sena’s central idea — evolution as horror — is strong enough to survive any genre translation. That is the common strand across every entry here: the concept outlives the container.

4. S.T.A.L.K.E.R. — The Strugatsky Brothers’ Roadside Picnic

Roadside Picnic (1972), by Soviet brothers Arkady and Boris Strugatsky, is one of the finest science fiction novels ever written. In its world, alien visitors stopped on Earth as casually as humans stop for a roadside meal, leaving behind ‘Zones’ littered with artifacts that obey no human physics. Scavengers called stalkers slip past military cordons to retrieve them. Andrei Tarkovsky filmed it as Stalker in 1979; nearly three decades later, Kyiv studio GSC Game World fused the novel’s vocabulary with the real geography of the Chornobyl exclusion zone for S.T.A.L.K.E.R.: Shadow of Chernobyl (2007).

The game barely names its debt, yet the novel’s fingerprints are everywhere: anomalies, artifacts, stalkers trading them in back-alley bars. Shadow of Chernobyl became a cult classic, spawned two follow-ups, and the franchise returned with S.T.A.L.K.E.R. 2: Heart of Chornobyl in 2024 — fifty-two years after the book’s publication. Few properties in any medium demonstrate that kind of half-life. The Zone keeps pulling people back, which is the highest compliment a fictional world can receive.

5. I Have No Mouth, and I Must Scream — Harlan Ellison

Harlan Ellison’s 1967 short story is nine thousand words of concentrated dread: a supercomputer named AM has exterminated humanity, sparing five survivors to torture for eternity, and it tells them so in the story’s immortal title line. The story won the Hugo Award in 1968 and has lost none of its power. In 1995, Ellison co-wrote and co-designed a point-and-click adventure game built directly on it — and voiced AM himself, delivering one of the most quietly frightening performances in the medium’s history.

The game matters because it proves author involvement pays. Rather than licensing the title and walking away, Ellison helped expand five character backstories into interlocking nightmare chapters, each built around its protagonist’s guilt. Few adaptations show an author this much trust in the new form, and almost none are better for the author’s fingerprints being all over them. For writers on EBOKIO, it is the model to aim for: keep your voice inside the adaptation, not at the door.

6. Dante’s Inferno — Dante Alighieri’s Seven-Hundred-Year-Old Hell

The oldest source on this list predates the printing press. Dante’s Inferno, the first third of The Divine Comedy (completed around 1321), remains literature’s most influential guided tour of hell — nine descending circles, each punishing a different sin with grotesque, geometric logic. Visceral Games and Electronic Arts adapted it in 2010, reimagining pilgrim Dante as a disillusioned crusader descending with a scythe to rescue the soul of Beatrice.

Purists objected, and not without reason: the game’s Dante fights where the poem’s Dante weeps. But the adaptation translated something real — the architecture. Lust’s storm, the wood of suicides, the frozen lake at the bottom where traitors lie locked in ice: level designers received a floor plan written seven centuries ago. Whatever its liberties, Dante’s Inferno put a medieval Italian poem on millions of consoles, and that counts as a service to literature.

7. Spec Ops: The Line — Joseph Conrad’s Heart of Darkness

Joseph Conrad published Heart of Darkness in 1899: a river journey into Central Africa that becomes a journey into moral collapse, ending with the dying Mr. Kurtz whispering, ‘The horror.’ Francis Ford Coppola transplanted it to Vietnam for Apocalypse Now; in 2012, Berlin studio Yager Development concluded the chain with Spec Ops: The Line, moving the descent to a Dubai swallowed by sandstorms.

What sets The Line apart is its relationship with the player. Where most war games reward aggression, this one punishes you for acting like a video game hero — most notoriously in the white phosphorus sequence, where the camera forces you to inspect the aftermath of your own approved airstrike. It is Conrad’s thesis rebuilt as mechanics: given power without oversight, the ‘civilized’ man becomes the horror. It remains the standard example of adaptation as criticism — not borrowing a book’s setting, but borrowing its argument.

What Readers Should Take From This

If you played any of these games and never touched the source, you are holding half the story. Reading Roadside Picnic after Shadow of Chernobyl changes the Zone from a backdrop into a philosophical trap. Opening The Witcher saga after Wild Hunt shows you where Geralt’s deadpan humor was minted. The relationship runs both directions, and readers win either way: the game becomes the world’s most elaborate spoiler-free trailer, and the book fills in the interiority no engine can render.

On EBOKIO’s marketplace ( https://ebokio.com/ ), we build collections around exactly this instinct — fantasy sagas, post-apocalyptic fiction, and classic literature in digital formats, including titles by independent authors working in the traditions these adaptations drew from. Because EBOKIO is a marketplace and publisher in one, you are often reading the next crossover candidate before any studio has heard of it.

What This Means for Authors — and Where EBOKIO Fits

Every game above began as a text file on someone’s desk. Nothing about Sapkowski’s contest entry or Glukhovsky’s free website chapters guaranteed an adaptation; what they shared was a built, coherent world. Adaptation studios license worlds, not manuscripts. If you write fiction today, treat worldbuilding as an asset class: consistent maps, rules, chronicles, and character bibles are what a licensing team actually evaluates.

Distribution is the other half of the equation, and here the comparison between platforms matters. On a generalist mega-storefront, an independent novel competes against millions of titles, and its visibility depends on advertising spend rather than craft. On EBOKIO, titles are surfaced through curated genre collections and editorial features — discoverability by selection, not by ad budget. For an author whose book might one day catch a game designer’s eye — and game designers are exactly the kind of browsing reader curation attracts — that difference is structural.

The economics differ as well. Author onboarding at EBOKIO ( https://ebokio.com/ ) is built for working writers rather than account administrators: straightforward listing, transparent terms, and international payments handled through trusted rails such as Stripe, PayPal, and Wise — the same infrastructure EBOKIO itself runs on as a UK-registered company (EBOKIO LTD). Compare that to mass platforms where royalty calculations shift across pricing tiers, delivery fee deductions, and payout thresholds buried in help-center articles. A novelist planning a long career — sequels, translations, licensing — needs a publishing partner whose incentives stay legible over years, not a black box that re-prices them quarterly.

Finally, there is reach. Glukhovsky was ‘discovered’ globally because his 2010 English edition shipped beside the game; Sapkowski’s translations followed the first game’s success. International digital distribution is now the default route to that kind of break, and it is precisely the route EBOKIO is built on: publish once, sell worldwide, keep your rights, and let the world you built find the readers — and maybe the developers — who want to live in it.

The Last Page Is Not the End

Seven books, seven games, one pattern: strong worlds migrate. They move from print to screen to controller because audiences refuse to leave them, and because each new medium reveals something the last one couldn’t hold — cinema the image, games the choice. The distance between Sapkowski’s typewriter and seventy-five million game sales is not an anomaly. It is a map.

Whether you arrive as a reader hunting for the original text behind your favorite game, or as an author building the kind of world that someday outgrows its pages, digital publishing is where that migration now begins. EBOKIO exists to make that starting point fair, global, and author-first. The next entry on a list like this one is being written tonight, quite possibly by someone with a storefront and no gatekeepers between their world and yours.

Frequently Asked Questions

Which video game based on a book has sold the most copies?

CD Projekt Red’s The Witcher series leads the category by a wide margin, with over 75 million units sold by March 2023 — more than 50 million of them from The Witcher 3: Wild Hunt alone. No other book-derived game franchise comes close to those figures.

Are the games faithful to the books they’re based on?

Rarely, and that is by design. The Witcher games are non-canonical sequels, Parasite Eve is a continuation set on another continent, and Spec Ops: The Line borrows Heart of Darkness as an argument rather than a plot. The strongest adaptations translate a book’s idea into playable systems instead of retelling its chapters.

Do I need to read the book before playing the game?

No — every game on this list stands on its own. Reading the source afterward adds depth rather than prerequisites. Many players report that the book recontextualizes the game: the Metro novels make 4A Games’ tunnels feel inhabited, and Roadside Picnic turns the S.T.A.L.K.E.R. Zone from scenery into philosophy.

Where can I buy these books as ebooks?

Classic sources like The Divine Comedy and Heart of Darkness are public domain and widely available. Modern works such as The Witcher and Metro novels are sold through major ebook retailers, and you can discover comparable fantasy and post-apocalyptic titles from independent authors on EBOKIO’s marketplace at ebokio.com .

Can an independent author’s book realistically become a video game?

The precedents are encouraging: Metro 2033 began as free chapters posted online, and The Witcher began as a contest short story. Studios license coherent worlds with proven readerships, not publishing pedigrees. What an indie author needs is a visible, rights-clean body of work on a platform with real distribution — which is the gap EBOKIO was built to close.

Do authors keep creative control when their book becomes a game?

It depends on the license. Andrzej Sapkowski had no involvement with The Witcher games, while Harlan Ellison co-designed his adaptation and voiced its villain. Negotiating involvement — or at minimum consultation rights — is a standard point in adaptation contracts, and another reason authors should retain and organize their rights from day one.

Notes

•All sales figures are the most recently reported numbers as of publication: The Witcher series passed 75 million units by March 2023 (over 50 million from Wild Hunt); the books exceeded 15 million copies with translations in 37 languages.

•The 562 percent book-revenue rise reflects the two weeks following the Netflix series launch in December 2019, compared with the same period in 2018.

•Metro 2033’s English-language edition was deliberately timed to the game’s 2010 release. Dmitry Glukhovsky chose the game medium over film for greater artistic freedom and served as scriptwriter on Metro: Last Light.
