10 Best Simulation Games on Steam (July 2026)

The Sims 4 remains a household name among the best simulation games on Steam, where players enjoy complete freedom over controlling the day-to-day lives of in-game characters. 

However, the simulation genre has evolved to include niche games, where you can be a deep-sea diver in Subnautica, a certified aviation pilot in Microsoft Flight Simulator, and an architect in Cities: Skylines II. 

Find the full list of the best simulation games on Steam below.

What is a Simulation Game?

A simulation game mimics an activity or role from the real-world. It lets you experience what it’s like to complete day-to-day tasks within the role. You’ll have daily objectives that help bring a project to its completion.

A mouse-and-keyboard combo is perfectly suited for the best simulation games on Steam, allowing you to easily juggle resource management, job assignments, and complete daily tasks.

10. Cities: Skylines

The best city-building games that had me hooked were always about building a civilization from scratch. Often set in medieval times, when the greatest empires rose to leave their marks on history. Until Cities: Skylines stepped in and showed me just how much fun building a modern city can be.

There are a lot of building blocks that make a city like New York run, and Cities: Skylines II is about building and managing all those systems. From setting up the road networks to the infrastructure and channeling people and businesses into your new megapolis, you’ll discover just what it takes to create a city that never sleeps.

9. Satisfactory

While I’ve played a couple of factory-building simulation games, none quite caught my eye and attention until I landed on Satisfactory. The scenario itself is perfect for building suspense and intrigue, where you’ve just landed on an alien planet and need to build factories for survival. 

You’ll need to automate resource gathering before moving to production lines so massive that they require multiple conveyor belts and multi-story buildings. But the game also has side missions where you explore the world, potentially running into hostiles you’ll need to fight.

8. People Playground

People Playground reminds me of the curiosity I had as a kid, mixing all sorts of products that, looking back, could have been potential hazards. In my adult years, I’m grateful to have People Playground devise a safe space to go nuts with science experiments. 

Careful before downloading this one, though, as it can get pretty violent. You experiment on ragdolls and can practically do whatever you want to test your gadgets and inventions before they’re ready to sell on the black market.

7. Stardew Valley

Gardening isn’t my thing. I’ve tried it, and the end-result just wasn’t as flourishing as I’d hoped. And so, I’ve resorted to farming simulations that surprisingly still elicit similar feelings of calm and relaxation.

And I think Stardew Valley players will agree with me that it deserves a spot among the best simulation games on Steam, just by the sheer wealth of things to do, from farming itself to running businesses and even dungeon-crawling.

6. Euro Truck Simulator 2

Trucking is a lifestyle, one you can definitely experience what it’s like in Euro Truck Simulator 2. The game caters to two core principles: building your favorite truck and enjoying the savanna while traveling across Europe. 

You’ll unlock multiple trucks that you can fine-tune their performance and style, as well as optional beacons and smoke exhausts. Thereafter, you’ll deliver cargo across thousands of miles of real-world roads, passing by landmarks and famous structures.

5. Company of Heroes 2: Ardennes Assault

In the frozen wilderness, an elite squad prepares for the greatest American battle of World War II, known as The Battle of the Bulge. You control US Allied Forces, completing tactical challenges in harsh terrain. 

Company of Heroes 2: Ardennes Assault stands out among the best simulation games on Steam for its focus on telling a dramatic campaign, which switches perspectives between three different officers with unique struggles and making tough decisions that impact their future.

4. The Sims 4

The level of customization is perhaps the feature that drew me most to The Sims 4. How the series goes beyond creating unique Sims to spelling out every detail of their homes. And even beyond, when you’re in complete control over their lives, whether it’s within their family unit, their relationships at work, or any extracurricular activities with other Sims.

3. MiSide

MiSide may start with a relatively simplistic story, but it grows darker pretty fast. You’re initially helping an in-game character carry out their chores. But they mysteriously drag you into their world, leaving you with no way out. 

If you can be patient with it, I think you’ll find the story pretty thought-provoking. It’s the kind that has you settle into a warm, cozy vibe, only to gradually build psychological tension that grows more sinister by the end.

2. Microsoft Flight Simulator 2024

If you’ve ever had any slight interest in aviation, Microsoft Flight Simulator is the place to be. Boasting the highest number of aircraft, and not just fictional ones, but real-life planes. They cut across all branches of aviation, be it search and rescue, medevac, or remote cargo ops, and take you through the path to earning a certification in each field.

Thus, the challenges in Microsoft Flight Simulator will keep you engaged for a good while, with sub-categories around racing, low-altitude flying, precision landing, and more.

1. Subnautica

I haven’t yet mastered the courage to swim to the depths of the ocean. But Subnautica already has me excited about the day I finally have a go at it. It’s a beautifully designed game, immersing you in a stunning aquatic world of both marine and alien life.

It truly is a whole world in the deep sea, with volcanoes, complex caves, coral reefs, and the diverse aquatic species that live within. While it’s easy to get carried away exploring, you also need to scavenge and craft resources if you’re to survive living underwater.
