Whether it’s a highly sought-after planet, a dystopian treasure hunt, or an existential journey to discover the meaning of life, the genre is at its most entertaining when its imagination runs wild. From the spice-covered deserts of Arrakis to a dystopian treasure hunt built around classic video games, these stories turn their wildest ideas into genuinely exhilarating adventures. If you’re looking for sci-fi that embraces the thrill of the journey without sacrificing imagination, here are five of the most entertaining books in the genre. 5 'Project Hail Mary' (2021) Image viaa Ballantine Books Though many know it from its hit 2026 adaptation, Project Hail Mary is originally a sci-fi novel that tells the same story through Andy Weir's words. Right from the get-go, readers are whisked away into an unknown adventure through the eyes of Ryland Grace, who wakes up inside a distant spacecraft. He doesn't remember his name, his mission, or the events leading up to his rocket launch. But soon enough, he discovers that he's the missing puzzle piece in a desperate mission to save Earth from a Sun-consuming organism that threatens to end the world as people know it. The apocalyptic appeal sends major Armageddon vibes, but the real excitement comes from Ryland's adventure itself. A scientist by profession, Ryland must draw on his extensive but previously belittled knowledge of the organism to test his way out of lethal situations using actual scientific methods, without overwhelming readers with complicated technical details. At a moment when humanity is on the brink of extinction, connection is most needed. Even when he's the only human in space, he finds the most genuine connection with a creature he least expects, providing the novel with its much-needed emotional anchor and giving all the more reason to root for Ryland. 4 'Ready Player One' (2011) Image via Crown Publishing Group Ready Player One is set in a poverty-stricken 2040s. Humanity escapes a world ravaged by energy shortages, pollution, and economic stagnation through the OASIS, a virtual universe created by billionaire James Halliday. Upon his death, Halliday leaves behind a challenge: whoever finds three hidden keys and unlocks his Easter egg will inherit his fortune and control of the OASIS. Five years later, 18-year-old Wade Watts, a gunter living in Oklahoma City’s trailer stacks, discovers the first key through his knowledge of Halliday’s beloved 1980s pop culture. As he races against rival hunters and a corporation seeking to seize the OASIS, Wade’s quest transforms into a fight for humanity’s last refuge. It's the ultimate treasure hunt in Ready Player One. On top of the satisfaction of solving puzzles, readers can't help but feel like they're part of a video game themselves. What makes the quest unique is how the knowledge needed to solve its puzzles contrasts with its futuristic setting. If you're a fan of classic arcade games, geek culture, Dungeons & Dragons, and the like, your expertise will come in handy. Ready Player One is ultimately a celebration of geek culture. One moment, Wade might be playing an arcade game; the next, he's piloting a spaceship or exploring a fantasy world. It's a nostalgic adventure for geeks everywhere. Collider Exclusive · Sci-Fi Survival Quiz Which Sci-Fi World Would You Survive? The Matrix · Mad Max · Blade Runner · Dune · Star Wars Five universes. Five completely different ways the future went wrong — or sideways, or up in flames. Only one of them is the world your instincts were built for. Eight questions will figure out which dystopia, galaxy, or desert wasteland you'd actually make it out of alive. 💊The Matrix 🔥Mad Max 🌧️Blade Runner 🏜️Dune 🚀Star Wars TEST YOUR SURVIVAL → 01 You sense something is deeply wrong with the world around you. What do you do? The first instinct is often the truest one. APull on every thread until I understand the system — then figure out how to break it. BStop asking questions and start stockpiling — food, fuel, weapons. Questions don't keep you alive. CKeep my head down, observe carefully, and trust no one until I know who's pulling the strings. DStudy the patterns. Every system has a rhythm — learn it, and you learn how to survive it. EFind the people fighting back and join them. You can't fix a broken galaxy alone. NEXT QUESTION → 02 In a world of scarcity, what resource do you guard most fiercely? What we protect reveals what we believe survival actually requires. AKnowledge. If you understand the system, you don't need resources — you can generate them. BFuel. Everything else — movement, power, escape — runs on it. CTrust. In a world of fakes and informants, a truly reliable ally is rarer than any commodity. DWater. And after water, information — the two things empires are truly built on. EShips and credits. The galaxy is big — you survive it by being able to move through it freely. NEXT QUESTION → 03 What kind of threat keeps you up at night? Fear is useful data — if you're honest about what you're actually afraid of. AThat reality itself is a lie — that everything I experience has been constructed to keep me compliant. BA raid. No warning, no mercy — just the roar of engines and then nothing left. CBeing identified. Once someone with power decides you're a problem, you're already out of time. DBeing outmanoeuvred — losing a political game I didn't even know I was playing. EThe Empire tightening its grip until there's nowhere left to run. NEXT QUESTION → 04 How do you deal with authority you don't trust? Every dystopia has a power structure. Your approach to it determines everything. ASubvert it from the inside — learn its rules well enough to weaponise them against it. BIgnore it and stay out of its reach. The further from any power structure, the better. CAppear to comply while doing exactly what I need to do. Visibility is the enemy. DManoeuvre within it carefully. You can't beat a system you refuse to understand. EResist openly when I have to. Some things are worth the risk of being seen. NEXT QUESTION → 05 Which environment could you actually endure long-term? Survival isn't just tactical — it's physical, psychological, and very much about where you are. AUnderground bunkers and server rooms — cramped, artificial, but with access to everything that matters. BOpen wasteland — brutal sun, no shelter, constant movement. At least the threat is honest. CA dense, rain-soaked city where you can disappear into the crowd and nobody asks questions. DMerciless desert — extreme heat, no water, and something enormous living beneath the sand. EThe fringe — backwater planets and busy spaceports where the Empire's attention rarely reaches. NEXT QUESTION → 06 Who do you want in your corner when things fall apart? The company you keep is the clearest signal of who you actually are. AA tight crew of believers who've seen behind the curtain and have nothing left to lose. BOne or two people I'd trust with my life. Any more than that and someone talks. CNobody, ideally. Alliances are liabilities. I work alone unless I have no choice. DA community bound by shared hardship and mutual survival — people who need each other to last. EA ragtag team with wildly different skills and total commitment when it counts. NEXT QUESTION → 07 Where do you draw the line — if you draw one at all? Every survivor eventually faces a moment that tests what they're actually made of. AI won't harm the innocent — even the ones who'd report me without hesitation. BI do what I have to to protect the people I've chosen. Everything else is negotiable. CThe line shifts depending on who's asking and what's at stake. DI draw a long-term line — nothing that compromises my people's future, even if it'd help now. ESome lines, once crossed, can't be uncrossed. I know which ones they are. NEXT QUESTION → 08 What would actually make survival worth it? Staying alive is one thing. Having a reason to is another. AWaking others up — dismantling the illusion so no one else has to live inside it. BFinding somewhere — or someone — worth protecting. A reason to keep moving. CAnswers. Understanding what I am, what any of this means, before time runs out. DLegacy — shaping the future in a way that outlasts me by generations. EFreedom — for myself, for others, for every world still living under someone else's boot. REVEAL MY WORLD → Your Fate Has Been Calculated You'd Survive In…Your answers point to the world your instincts were built for. This is the universe your temperament, your survival instincts, and your particular brand of stubbornness were made for. The MatrixYou took the red pill a long time ago — probably before anyone offered it to you. You're a systems thinker who can't help but notice the seams in things. You're drawn to understanding how the system works before figuring out how to break it. You'd find the Resistance, or it would find you — your instinct for spotting constructed realities is the machines' worst nightmare. You function best when you have access to information and the freedom to act on it. The Matrix built an airtight prison. You'd be the one probing the walls for the door. Mad MaxThe wasteland doesn't reward the clever or the well-connected — it rewards those who are hard to kill and harder to break. That's you. You don't need comfort, community, or a cause larger than the next horizon. You need a vehicle, a clear threat, and enough fuel to outrun it — and you're good at all three. You are unsentimental enough to survive that world, and decent enough — just barely — to be something more than another raider. In the wasteland, that distinction is everything. Blade RunnerYou'd survive here because you know how to exist in moral grey areas without losing yourself completely. You read people accurately, keep your circle small, and ask the questions others prefer not to answer. In a city where humanity is a legal designation rather than a feeling, you hold onto something that keeps you functional. You're not a hero. But you're not lost, either. In Blade Runner's world, that distinction is everything. DuneArrakis is the most hostile environment in the known universe — and you are precisely the kind of person it rewards. Patience, discipline, and political awareness are your core strengths — and on Arrakis, they're survival tools. You understand that the long game matters more than any single victory. Others come to Dune and are consumed by it. You'd learn its logic and earn its respect. In time, you wouldn't just survive Arrakis — you'd begin to reshape it. Star WarsThe galaxy far, far away is vast, loud, and in a constant state of violent political upheaval — and you wouldn't have it any other way. You find meaning in being part of something larger than yourself — a cause, a crew, a rebellion. You'd gravitate toward the Rebellion, or the fringes, or whatever pocket of the galaxy still believes the Empire's grip can be broken. You fight — not because you have to, but because standing aside isn't something you're capable of. In Star Wars, that willingness is what makes all the difference. ↻ RETAKE THE QUIZ 3 'Dune' (1965) Image via Penguin Publishing Group The Oscar-winning sci-fi hit Dune is a tumultuous tale of prophecy and fulfilling one's destiny. When Duke Leto Atreides is ordered to take control of Arrakis, the galaxy’s most valuable desert planet, he knows something isn't right. Arrakis is the only source of spice, a powerful substance that extends life and makes interstellar travel possible, making the planet a prime target for anyone seeking power. Along with his partner, Lady Jessica, and their son, Paul, Leto soon finds himself caught in a dangerous political game involving the Emperor and their longtime enemies, House Harkonnen. But little does Paul realize that his prophetic dreams are key to saving the kingdom. More than half a century later, Dune still holds up thanks to the sheer scale and imagination of its worldbuilding. It doesn't take long for author Frank Herbert to throw readers into the middle of the conflict. Similar to the medieval disputes akin to Game of Thrones, readers are caught between warring noble families, desert politics, and the occasional giant sandworm. Arrakis itself is a character of its own, and the book describes the universe surrounding the planet, from the ancient Fremen culture to the politics that dictate the spice trade. It's dense and loaded, but it's the kind of packed that immerses you so deeply that you'll feel like you're in Arrakis yourself. 2 'Ender's Game' (1985) Image via Tor Books Ender’s Game is essential sci-fi reading. With Earth threatened by an insect-like alien race known as the Buggers, the International Fleet turns to gifted children to prepare for another invasion. Andrew “Ender” Wiggin is recruited into Battle School after proving he can outsmart his bullies. Despite being isolated and pushed to his limits by Colonel Graff, Ender becomes one of the school’s best commanders, mastering zero-gravity war games with unconventional tactics. Promoted to Command School, Ender trains under war hero Mazer Rackham. Ender’s Game is essentially a battle playbook. But instead of focusing on the theatrics of entering battle, it gives readers the lowdown on all the mental preparation required before stepping onto the field. It takes more than brawn and weapons to defeat your enemies; true battle comes down to strategy, knowing your enemy, and choosing the most efficient methods to achieve the greatest success with minimal casualties. Ender may have started weak and vulnerable, but watching him grow through his loyalty to his troops, his willingness to study the craft, and his ability to adapt makes the book a fun read in itself. With the guidance — and sometimes the pressure — of Battle School, Ender gradually learns that winning a fight is about understanding how to use every advantage at his disposal. 1 'The Hitchhiker's Guide to the Galaxy' (1979) Image via Pan Books Audiences who want a sci-fi adventure that doesn't take itself too seriously don't have to look any further than The Hitchhiker's Guide to the Galaxy. Author Douglas Adams introduces the seemingly ordinary Englishman Arthur Dent to an absurd space adventure after Earth is destroyed by the Vogons to make way for a hyperspace bypass. From there, Arthur travels across the galaxy with his alien friend Ford Prefect, the eccentric Zaphod Beeblebrox, the depressed robot Marvin, and Trillian, another human survivor. But Arthur has no time to dwell on his confusion, as his adventures lead him to uncover Earth's true purpose, which, fittingly enough, is orchestrated by a supercomputer. There is no telling where The Hitchhiker's Guide to the Galaxy is about to go. It's obvious that the author has every intention of making each page funny, and there's an unexplained absurdity to everything that constantly throws readers off as they try to figure out why certain things are happening. There's no particular explanation for why a hyperspace bypass requires destroying Earth's population or why two-headed presidents exist, which is exactly the point of the novel. Humanity is so fixated on finding the meaning of life, but the book stresses that life and the universe itself could barely care less about the answer. And when it finally provides its infamous answer, it's so unbelievably underwhelming that it's hilarious.
