10 Best Simulation Games on Steam (July 2026)

The best simulation games come in all shapes and forms, from the immersive maritime exploration and survival gameplay of Subnautica to the cozy farming simulation in Stardew Valley and the deep customization of the characters and homes of The Sims. You only need to identify a niche interest in the real-world to find it realized in gaming.

What is a Simulation Game?

A simulation game focuses on realistic takes on an activity. Often, you’ll complete objectives, broken down into easy-to-do tasks, which add up to accomplishing a bigger goal.

Best Simulation Games on Steam

No matter your unique taste and style, I’m certain you’ll find exactly what you’re looking for in the best simulation games on Steam below.

10. Cities: Skylines

You won’t find a modern city simulator as realistic and slick-looking as Cities: Skylines II. Cast into the role of the mayor, you’re tasked with building a 21st-century skyrise city from the ground up. 

The content in the game should keep you well busy, from the building and construction stage to setting up the infrastructure and policy-making. That’s right, it’s a full-circle city-building experience that tests both your architectural skills and urban planning.

9. Satisfactory

Factory-building is another branch of the best simulation games on Steam. Here, you’re responsible for gathering resources, setting up production chains, and automating those processes for optimum production.

However, Satisfactory has a leg up on the rest of the factory-building games you may have played before. It takes you to an alien world, where you explore for resources, solo or with friends, and might at times run into hostile enemies who instigate combat.

8. People Playground

You may be surprised to learn that People Playground also falls in the category of the best simulation games on Steam. As much as you’ll be dealing with ragdolls, the concept is based on the realistic testing of new technology before deployment.

Only that the technology you’re testing is military-grade weapons and equipment, and yes, the testing scenarios often get bloody. Get ready to enjoy cartoon gore in all its blood and guts spilling, be it stabbing, shooting, vaporizing, and more lethal avenues of violence.

7. Stardew Valley

On the quieter side of the best simulation games is Stardew Valley. The goal may seem a hundred miles away, but the steps to get there are feasible enough to execute one day at a time. 

From growing crops to selling them at the market and mining valuable treasure in the dungeons, you’ll soon have enough to transform your grandfather’s old farm plot into a bountiful garden.

6. Euro Truck Simulator 2

The European countryside has so much to see, and what better way to appreciate its beauty than behind the wheel of a slow-moving truck? Euro Truck Simulator 2 lets you drive across Europe, taking in all the historic and popular landmarks across Europe.

It charges you with making deliveries to often interesting folks. Moreover, you unlock trucks you might actually identify in real-life, with some of the most realistic driving and design.

5. Company of Heroes 2: Ardennes Assault

Military simulation is also another sub-genre you’re going to enjoy, and especially Company of Heroes 2: Ardennes Assault for its riveting campaign. War isn’t just about how brutal you are against the enemy. It’s about the friendships you form within your squad.

The battlefield is a theatre stage where plenty goes on in the background, and the single-player campaign here captures those intricacies between squad relationships, the hardships they face in a frozen wasteland, and how they rise above the fear of dying.

4. The Sims 4

As for life simulation, you’ll never go wrong with The Sims 4, no matter how many times you log back in. The customization systems for your Sims are so detailed and extensive that you can practically create Sims that look like anyone you want. 

But your Sims’ distinct features are even more appreciated when they act and behave like actual people. How they live their lives, relying on your gentle guidance to make friends, build a family, and achieve success in every aspect.

3. MiSide

For all of the best simulation games on Steam, MiSide may be the strangest one. But it’s weird in a gripping way, especially with how cute it starts before things go sideways. You’re in charge of taking care of an in-game character. You know, reminding them to brush their teeth, clean their room, and whatnot.

However, something unexpected happens when you suddenly become a part of their world. While it’s fun for a bit, you eventually want to leave, but the game doesn’t let you until you figure out the dark mystery that’s hidden beneath the shiny surface. 

2. Microsoft Flight Simulator 2024

Flying has to be the most exhilarating means of travel, and yet not everyone of us will enjoy the chance to sit in the cockpit and admire the clear blue skies. But that’s where Microsoft Flight Simulator comes in.

It’s the best simulation game for fans of aeronautical engineering and aviation, where you aren’t just in charge of flying your plane, but also performing maintenance checks every so often. Your plane is your baby, which you shouldn’t have a problem taking care of, given how impressively and realistically detailed they are compared to real-life planes.

1. Subnautica

I love swimming, but I’m not built for deep-sea diving. Hence, my spending too much time than I care to admit exploring Subnautica in the hopes that I’ll one day conquer my fears of the ocean depths, and what a journey it’s been. 

I’ve seen some of the most beautiful maritime species in this game, swimming around lush coral reefs and majestic cave systems. I have befriended some of the alien-looking species, and fought ones who craved for blood.

In your time here, you won’t just be a maritime explorer, but a survivor, too, crafting new equipment for your submarine and managing the scarce resources a life underwater has to offer.
