10 Best Simulation Games on Steam (October 2026)

Exploring the maritime coral reefs and cave networks in Subnautica feels like deep-sea diving in real-life, as is the truck-driving in Euro Truck Simulator. But beyond realism, the best simulation games on Steam offer intricate detail in the buildings and systems you create, such as the factories in Satisfactory and cities in Cities: Skylines II, along with more simulation games listed below.

What is a Simulation Game?

A simulation game mimics real-life in the characters’ lives, stories, and activities you get up to.

Best Simulation Games on Steam

So many of the best simulation games on Steam that are highlighted below have garnered high praise from critics and gamers alike.

10. Cities: Skylines

Building functionally independent cities is the foundation of Cities: Skylines II. However, the game offers so much more beyond city-building. It’s a space to creatively test out the wildest ideas you’ve ever dreamt of bringing to life and witnessing how those ideas might evolve communally.

The city is your brain-child, and from conception to its potentially infinite lifetime, you’re responsible for making sure its beating heart remains strong and healthy. From the buildings to the road networks and the people using them, the city thrives on your strategic planning and management of all its policies.

9. Satisfactory

An entire planet is yours to explore, excavate, and mark your territory in Satisfactory. An infinite supply of resources can be found from plants and animals, though some may be hostile, and you will have the weapons to defend yourself.

Ultimately, Satisfactory is a factory-building and simulation game. It has no limits to the scale and complexity of the factories you build. They can be multi-storied and have connecting conveyor belts. It truly is impressive how detailed the systems and tools for building and automating are.

8. People Playground

You rarely come across titles in the best simulation games on Steam as unique as People Playground. First of all, it’s going to get pretty bloody, but also, the spills are from ragdolls. No harm done to actual humans.

Intentional harm, or rather, testing of military tools and equipment. Before you can convince buyers to take you up on your new scientific invention offer, you must test how effective your weapon is in a large open space, purely for running dangerous and deadly experiments.

7. Stardew Valley

Stardew Valley will initially get you thinking that it’s a farming game, where you inherit your grandfather’s old farm and work on it with only a few hand-me-down tools, and the farm is a mess of overgrown weeds. 

Gradually, though, as your farm grows and you begin selling your produce at the market, the game opens up into a social simulation network of friends and family. Beyond, though, it challenges you to fearlessly conquer dungeons crawling with monsters and looting buried treasure.

6. Euro Truck Simulator 2

Euro Truck Simulator 2 is up next, for those with even a remote interest in truck driving. I think the controls and handling here will more than satisfy. It’s pretty realistic and feels like driving an actual truck, needing to steer around sharp corners, managing your speed, and braking 

For truck enthusiasts, you have so many real-life trucks you can unlock, with intricate detail on the bodywork and interior. You can manually adjust the controls, which are as intricate as manipulating the horns and lights, while also giving you a neat view of the miles, speedometer, and indicators. 

5. Company of Heroes 2: Ardennes Assault

Military simulation games vary in quality and experience. For Company of Heroes 2: Ardennes Assault, it leans more heavily into the tension and tumbling emotions of the moment-to-moment battle strategies. You’re a part of the US Allied Forces squad and must regain control over the Ardennes region.

You aren’t restricted to a strict mission structure and can move on enemies at your discretion. Ultimately, you have to defeat the German forces across 11 missions and seven engagements in the vicious and unrelenting Battle of the Bulge.

4. The Sims 4

We do have the freedom to get up to mischief and do whatever we want, but still with some restrictions on how to behave in certain places and institutions. The Sims 4 is the place, though, to let your birds, or Sims, out of their cage. 

Sims can have superpowers. You can have ghosts that haunt the community. Practically no rules apply to this goofy, vibrant, and chaotic world full of eccentric characters, unlimited drama, and wholesome lives. 

3. MiSide

But what if the in-game character you were in control of was hiding something? What if they were in danger? MiSide is a series of what-ifs that grow stranger the more time you spend in the game. It builds momentum, settling you into an everyday routine of cleaning stuff and putting dishes away.

2. Microsoft Flight Simulator 2024

The way Microsoft Flight Simulator is structured is as a pathway to building your aviation career. Starting from the simplest aircraft to flying commercial and industrial planes, you’ll climb the ladder of the aviation career and become a reputable professional in the field.

And it’s all simulated realistically, whether it’s the missions you complete, varying from search and rescues to cargo operations, or the aircraft models you unlock. The airstrips are also modeled after real ones, as are the environments you fly over.

1. Subnautica

Subnautica is a must-play among the best simulation games on Steam, merging survival with maritime exploration. As beautiful as the coral reefs are in the deep sea, there is dangerous wildlife you’ll have to defend yourself against. 

This calls for resource gathering and crafting in your submarine, which may also need bolstering of its defenses. You’re practically spending weeks underwater, so you also need water and food to survive.
