Game development has come a long way and has become one of the fastest-growing industries. The game development standards are high, and over time, the images and designs in the game look almost real.

When it comes to gaming applications, game developers use software development environments to develop interactive games, known as game engines. There are various gaming engines available in the market. Still, two major players are Unity 3D and Unreal Engine because popular games such as Pokémon Go (Unity 3D) and Fortnite (Unreal Engine) are developed using these gaming engines. These engines’ technology and skills in development and designing are far better than others in the market.

According to the study by MarketWatch, global game engine revenue will grow at 13% CAGR and will reach a valuation of $3650 billion by 2024 in comparison to USD 1760 million in 2019.

But still, there is confusion when it comes to choosing Unity vs Unreal engine. Today, Unity 3D has a 48% market share, whereas Unreal Engine has a 13% share. But deciding on an engine based on market share is not enough because these engines offer impressive offerings, and your decision must depend on your development requirements.

Similarities Between Unity and Unreal

Unity and Unreal can create AAA-quality graphics and have significant bridges between most industry-standard software. Also, these engines deliver a comprehensive toolbox including animation, VR Support, terrain editor, physics simulation &, etc.

What platforms do Unreal Engine and Unity support?

Unreal Engine supports the following platforms:

  • Windows PC
  • Xbox One
  • Nintendo Switch
  • Windows PC
  • Android
  • VR
  • PlayStation 4
  • SteamOS
  • MacOS

Differences Between Unity and Unreal

1. Unreal Engine is an available source, and Unity is a cross-platform game engine.

2. Unreal Engine uses C++, and Unity uses C#. And the language that is considered suitable for game development is C#.

3. Unreal Engine was launched in 1998, and Unity was released in 2005.

4. Both engines deliver good and detailed documentation demonstrating their tools and features.

5. Unity 3D Unreal engines have a vast community of active uses. However, Unity 3D has more additional clients and a user base.

6. Unreal Engine is free of cost, but you own royalties to them, whereas Unity is free, but the complete version requires a one-time fee of $1500 or $75/month.

7. Unity offers an extensive range of mods, i.e., 31000 assets compared to unreal, that is 10000.

8. Unreal Engine has an open-source Engine with an easy development process, and Unity, on the other hand, does not offer open-source code; but it can be purchased.

9. Unreal supports faster rendering, whereas rendering is slow in the case of Unity with slow processing of projects.

10. Unreal Engine is preferred over-unity due to its quality of graphics.

Which one to choose?

Before choosing between Unreal vs Unity engines, it is crucial to decide about your requirements, say what type of game to develop, such as 2D, 3D, virtual reality, etc. The first and foremost requirement is to go with a noble game development idea with a high revenue generation with quality graphics. It would help if you decided on all these aspects before you came up with selecting the right game engine.

Once you have finalized the game development idea and requirements, the next is deciding on the gaming engine and game development companies.

Best Game Engine for Your Mobile Game App

Game Engine Graphics:

Gaming is nothing without graphics, and mobile game development professionals give the best gaming experience through innovative game designing and development. And the best EngineEngine for graphics is Unreal Engine 4 due to its capability to design stunning and high-quality graphics with state-of-the-art 2D and 3D rendering approaches. And unity game development engines are not lacking behind in the case of high-level graphics, but the development process sometimes slows down.

Unreal Engine delivers high-fidelity graphics and high-performance to let developers create and yield great visuals for mobile games. In contrast, Unity can also build high-quality visuals but requires more struggle to get the assets right.

Thus, high performance and quicker effects blended with great visuals make Unreal Engine more popular than Unity, especially for big game productions.


Performance comes into play when we need to evaluate two-game engines side by side. Unreal Engine uses C++, while Unity uses C# as a programming language.

C++ delivers more developer control over memory management, and C# does not allow control of the memory management system.

While on the other hand, the Unreal mobile game Engine delivers myriad and amazing visual graphics and effects as well as features. Unity requires plugins to facilitate features to create impressive FX, animation, cinematics, etc.


Designer and developer requirements are quite distinct. Developers mostly look for a Unity engine as it is easy to access, offers excellent assets packaging, and the result is real-world-like visuals. At the same time, graphic designers look for visual quality and a controllable platform. Thus, both game engines are on the same level in functionality and capabilities.

Assets Stores :

To develop 3D assets from scratch, you need to use a 3D modeling software such as Blender, Maya, or 3ds Max; other assets are available on the Assets Store. Both gaming engines have asset markets from where you may purchase objects, environments,pre-made 3D models, and so on.

The number of assets in the Unreal Engine is around 10,000, whereas Unity Asset has around 31,000+ 3D assets. Unreal assets are acquainted with finished game productions. If you plan to develop a game with an appropriate fantasy or sci-fi setting, go for Unreal Engine 4.

And if you want to develop a VR application for business, where graphics quality isn’t important as relevance and iterative development, go with Unity.

Therefore, Unity 3D asset store is advanced in the case of assets, and Unreal Engine is catching up.

Pricing :

Both Unreal and Unity engines have some free parts, and others are chargeable. The full version of Unreal Engine 4 is free of cost if your game revenue is less than $3,000 /quarter; if more than 5% of the game’s gross revenue, you need to pay the additional fee.

The Unity Gaming Engine has a free personal plan that both individuals and small businesses can use. It offers two kinds of packages for larger businesses; plus, packages are used for businesses with revenue less than $200K in 1-year before purchase. The package is available on both monthly and annual subscriptions, monthly charges are $35 per month, and the annual subscription is priced at $299 on a prepaid basis.

Unreal Engine 4 is free and has no Pro version, but the royalty fee of 5% is connected to it if revenue exceeds $3000 in a quarter. Thus, developers and designers might rely on this model.

Apart from that, there are separate charges for iOS or Android game development. Thus, if you are planning a big app, then Unity 3D is a great option, but Unreal Engine is best with a simple or practical plan. But it depends on your preferences and choice of yours.

Is Unreal Harder Than Unity? :

Wheather unreal is harder, or Unity is a major concern among new developers and businesses looking to hire Unreal or Unity game development companies. There are thousands of developers working on Unreal/UE platforms.

The recent versions of the gaming engines are well-optimized. So it is easier to work on both platforms. But still, there will be confusion about which platform to choose. Still, many devs who have worked with both options concede that Unity is easier because it has simplified and understandable C# language.


Without Unity and Unreal engine two-game development tools, game development would be hard to imagine. Both have pros and cons, but the choice will depend upon the project’s requirements. Unity is known for its user performance development support, huge base, and for making 2D and 3D simulations. On the other hand, the unreal Engine is favored for building big games due to the beautiful graphics it offers.

Hiring a game app development company can be quite overwhelming, specifically when forming your game plan. So, it is best to carefully study these platforms and understand which platform can fulfill your app requirements.

Both Unreal and Unity engines are great game creation tools alike. It will be quite easy to decide which gaming engine is best for your gaming idea according to the above parameters.

However, both these engines are almost free, and if required, you can download both and test them out.
