Games have always been a wonderful medium for immersion into fantastical worlds, filled with wonder and marvel of the imagination. Science-fiction in particular has always been a genre that has thrived as a theme in gaming, with developers designing progressively more complex and immersive sci-fi worlds. Here's a list of the top 10 sci-fi games of all time that have brought us into fantastical realities beyond our wildest imaginations.

10. Mass Effect 2

The Mass Effect series is known for its storytelling, its characters, and its expansive universe. Its second installment, Mass Effect 2, is no exception to this rule. This game puts players in the shoes of Commander Shepard as they travel across the galaxy to stop a group known as the Collectors. With deep dialogue trees, customizable characters, and tons of player choice, Mass Effect 2 stands out as a seminal game in the RPG genre.

9. Halo: Combat Evolved

The Xbox's premier launch title, Halo: Combat Evolved, was a marvel when it first hit store shelves. Its gameplay mechanics were ahead of their time for console FPS, with tight shooting mechanics, a huge variety of weapons, and stunning graphics that ran without a hitch. The game's story, concerning a genetically-enhanced super soldier named Master Chief fighting off an alien race known as the Covenant, remains iconic to this day.

8. Deus Ex

The year is 2052 and the world is in chaos. Corporations hold more power than governments and a deadly virus called the Grey Death is spreading. In the midst of all this, you are JC Denton, a UN Anti-Terrorist Coalition agent tasked with stopping a nefarious organization known as Majestic 12 from carrying out a sinister plot. Deus Ex is a game that provides players with choice and freedom, allowing them to tackle problems and challenges in any way they see fit.

7. System Shock 2

System Shock 2 is often considered the precursor to first-person horror games like Bioshock and Dead Space. Players take on the role of a soldier awoken from cryogenic sleep aboard the Von Braun, a spaceship overrun with the nightmarish creatures that once served as its crew. In true horror fashion, resources are scarce and enemies are plentiful, forcing players to make tough choices about when to fight and when to flee.

6. Star Wars: Knights of the Old Republic

In this groundbreaking RPG, you take on the role of a Jedi warrior fighting in the galaxy's most infamous war. Along the way, you'll meet characters both good and evil, and the decisions you make will determine the fate of the galaxy. What makes Knights of the Old Republic stand out is its characters and its world-building, bringing the Star Wars universe to life in a way that no game before or since has managed.

5. Half-Life 2

In Half-Life 2, players return to the role of Gordon Freeman, the brilliant scientist who—through no fault of his own—unleashed a multidimensional menace upon the world. Half-Life 2 boasts exceptional visuals, excellent level design, and an immersive story that keeps players hooked from beginning to end. It's no wonder that the Half-Life series is still lauded as some of the best sci-fi gaming out there.

4. The Elder Scrolls V: Skyrim

While not strictly a sci-fi game, Skyrim is still an incredible work of world-building and immersive gameplay. Players take on the role of the Dragonborn, a character destined to fight dragons and civil war alike across the snowy expanse of Tamriel. Skyrim's magic, its characters, and its open-world design make it a game that's still played by millions of players each year.

3. BioShock

BioShock took the gaming world by storm when it was released, with its incredible story and immersive world-building that still holds up today. Players find themselves trapped in the underwater city of Rapture, a place founded on Objectivist principles where technology and genetic manipulation have gone awry. BioShock's visuals, its unique setting, and its memorable cast of characters make it one of the best games of all time.

2. Portal 2

The original Portal was a puzzle game like no other, but Portal 2 took everything that made the first game great and expanded upon it. Players take on the role of a test subject named Chell as she navigates the labyrinthine halls of Aperture Labs, solving puzzles and facing off against the maniacal robot GLaDOS. With its exceptional writing, tight gameplay, and intricate level design, Portal 2 is an unforgettable experience from beginning to end.
