Best Indie Sci-Fi Sandbox Games

Key Takeaways

  • Sci-fi sandbox games offer diverse experiences beyond traditional open-world activities
  • Star Valor and Stellar Tactics offer unique RPG experiences within open-world space sandboxes.
  • Shadows Of Doubt immerses players in a fully-simulated sci-fi city for detective work.

As a seasoned gamer with over three decades under my belt, I must say that the current gaming landscape is more vibrant and diverse than ever before. Among the many titles that have caught my eye recently, there are three games that stand out as particularly immersive and engaging experiences.


As a diehard fan, I’ve always found science fiction games and sandbox titles sharing a special bond. Titles like Freelancer have been my go-to for years, offering me vast cosmic realms to traverse and endless activities to indulge in. Usually, these involve mining asteroids, hunting down bounties, and trading goods.

While not every game labeled as a sci-fi sandbox fits this description perfectly, it’s important to note that the term “sandbox” can encompass various genres, including science fiction. For instance, the detective simulator Shadows of Doubt may not align completely with traditional sci-fi sandbox games, but its futuristic neo-noir city is imbued with science-fiction elements. Sandbox games are known for their lack of strict objectives or, at minimum, offering players flexibility in how they approach tasks. This design encourages creative problem-solving, enabling players to devise unique strategies instead of following a predetermined route towards an expected outcome.

6 Star Valor

An ARPG Space Sandbox With Faction Play & Ship Customization

  • Platform(s): PC
  • Released: 2022
  • Developer(s): Rafael Burgos
  • Genre: RPG

In simpler terms, this space-set action role-playing game (RPG) offers an expansive, open-ended environment for you to freely traverse using your spaceship. You’ll embark on a journey, uncovering the storyline as you go while also striving to accumulate wealth. It shares some similarities with loot-based RPGs like Diablo but has a more open-structured design, resembling games such as Mount & Blade.

Customizing ships is one of the standout aspects of the game, Star Valor. It boasts a crafting system, a wealth of loot to unearth, and more than eighty ship options to select. The game also offers faction play, mining, and trading, creating a varied gaming experience that’s seldom boring.

5 Stellar Tactics

An Open-World Squad-Based Sci-Fi RPG

  • Platform(s): PC
  • Released: 2016
  • Developer(s): Maverick Games
  • Genre: RPG

Regardless of having a modest budget typical of independent games, Stellar Tactics shines through with its wide range of gameplay options and rich content. While the tactical turn-based ground combat may become repetitive at times, Stellar Tactics compensates for this with an engaging world to delve into and a strong emphasis on player freedom.

In the game “Stellar Tactics,” players assume the job of interstellar mercenaries. The unique classless progression system in this role-playing game (RPG) lets players blend numerous skills to customize each character individually. The game offers a primary narrative, but it also embraces the open-ended style of space sandboxes by allowing players to mine asteroids and trade resources. However, combat remains a significant aspect of the game, making it an RPG with a strong focus on battle sequences.

4 Shadows Of Doubt

Solving Crimes In A Fully-Simulated Sci-Fi City

Despite being a comprehensive detective simulator, Shadows Of Doubt is set within a meticulously designed and procedurally generated sci-fi urban landscape bathed in neo-noir aesthetics. The game’s stylized visuals and thick atmosphere make traversing the city an engaging journey, with its immersive-sim mechanics further enhancing this experience.

In the game, players work on solving murder mysteries by navigating a completely realistic city, interacting with various non-player characters (NPCs), and utilizing different tools or gadgets. Because of its immersive features and emphasis on simulation, players can approach case solutions in their unique ways, creating a rich and open environment for gameplay. The release date for Shadows Of Doubt, the culmination of its Early Access phase, is set for the 26th of September.

3 Ostranauts

A Detailed But Inaccessible Sci-Fi Simulation

  • Platform(s): PC
  • Released: 2020
  • Developer(s): Blue Bottle Games
  • Genre: Simulation

Developed by the same creator as the turn-based survival game Neo Scavenger, Ostranauts is an exceptionally challenging sci-fi simulation where players explore and salvage gigantic space wrecks. This game boasts numerous intricate systems and complex mechanics that contribute to its immersive nature, albeit making it rather difficult for beginners. Despite its steep learning curve, the captivating mechanics and overall atmosphere make Ostranauts a game worth giving a shot.

It’s clear that the game Ostranauts offers a leisurely journey with a focus on exploration and gathering resources, but due to being in Early Access, it has some rough spots. Yet, its grand ambition and unique creative vision cater to a specific type of gaming niche.

2 Star Traders: Frontiers

Freedom & Dual Combat Systems In An Open-World Galaxy

As a space enthusiast, I can’t help but be captivated by the boundless freedom offered in “Star Traders: Frontiers.” This RPG throws me into an expansive galaxy teeming with strife, where I get to design my own starship and its crew, assuming the persona of a roaming freelancer. The game is brimming with activities, from clandestine smuggling and lucrative bounty-hunting to profitable trading or even daring piracy.

Star Traders: Frontiers boasts two distinct types of combat: one for space battles between ships, and another for ground encounters. Additionally, the game offers intricate ship and crew customization, as well as traditional RPG development, fostering a strong emotional bond with the player’s vessel and its crew.

1 RimWorld

A Colony-Sim Sandbox In A Sci-Fi Wild West

As a passionate enthusiast, I’d describe RimWorld as an immersive, multi-layered sandbox that challenges me to thrive in its challenging terrain using my own strategies. At the outset, I find myself leading a group of struggling settlers, constructing and overseeing a one-of-a-kind colony while warding off ferocious wildlife and relentless raiders. As the game progresses, my colony expands, and the task of protecting everyone grows more daunting, making each victory all the sweeter.

This colony-simulator game, while sparse in visuals, is richly atmospheric due to its expressive music and intricate sound design. The blend of acoustic guitar melodies with haunting ambience, along with a Western frontier vibe, gives off a sci-fi feel reminiscent of the beloved series Firefly.
