Unity vs. Unreal: The Ultimate Showdown of 2024

Unity and Unreal Engine are two leading game engines used extensively by game developers around the globe. Unity vs Unreal comparison continues to occur as both engines are known for their similarities in delivering great gaming experiences.

According to recent statistics, Unity has a 60% market share in mobile and web games. With its high-end graphics, Unreal Engine has been used for developing many globally popular AAA games.

Ultimately, choosing between Unity and Unreal Engine depends on several factors, particularly the specific needs of the game project. To make your choice of gaming solutions easier, we compare these two engines below.

What is Unity Game Engine?

Unity creates video games and other apps with interactive experiences across devices and OS platforms. Apps built by a specialist Unity game development company can run on desktop, mobile, gaming consoles, and virtual reality devices.

Unity with the largest market share among all game engines, can be found in thousands of top game titles across platforms. Some of the most acclaimed games built using the Unity engine include Hollow Knight, Ori and the Blind Forest, Cuphead, Pokemon Go, Kerbal Space Program, Rust, Superhot, Firewatch, Monument Valley and many others.

Let’s take a closer look at the pros and cons of using Unity as a game engine:

Pros:

• Cross-platform Support: Unity can create games for all major platforms using a single codebase. This saves development time and effort for game app projects.
• Extensive Community Support: Unity, with an extensive community of developers, ensures a wealth of resources and continuous support. Game developers can access tutorials, sample code, modules and knowledge on particular issues through forums, blogs, and other resources.
• Robust Official Support: Unity also offers good official documentation and always-available support through its website.
• Smooth Interface: Unity’s interface is smooth and intuitive, helping new developers start their Unity game project. Drag-and-drop functionality helps game object and asset building faster without writing any code.
• Asset Store: Unity comes with an extensive asset store offering a wide range of pre-built assets, tools, and plugins. This allows developers to add features to their games, and they don’t need to create everything from scratch.
• Support for Several Languages: Unity supports leading scripting languages such as C#, JavaScript, and Boo. This ensures optimum flexibility for developers.

Cons:

• Performance Glitches: Unity is often considered a wrong choice for resource-consuming and high-performance games. Unity is often slow and memory-intensive and can easily lead to performance issues.
• Not Fully-fledged 3D Capabilities: The 3D capabilities are less advanced than other leading game engines. The Engine is not fully optimized for cutting-edge 3D graphics and visual effects.
• Higher Learning Curve: Though Unity is regarded as user-friendly, the Engine’s advanced features can be difficult to learn. This can mainly be a challenge for new game developers.
• Default Splash Screen: The free version will show a Unity splash screen at the start of the game. This prevents creating a professional look and feels for games built with the free version.
• Subscription Fees: Though Unity has a free version, paying a subscription fee becomes a compulsion for developers needing advanced features.

What is Unreal Engine

Unreal Engine, created and maintained by Epic Games, is known for developing the world’s most famous large-scale video games with rich and other immersive experiences. With advanced graphics capabilities, it has been used to build the most successful AAA games.

Over the years, Unreal Engine has been used to build many popular and widely benchmarked titles in the gaming world. Some of the most popular games developed using Unreal Engine include Fortnite, Gears of War, Unreal Tournament, Batman: Arkham Asylum, BioShock, Rocket League, PUBG (playerunknown’s Battlegrounds), The Walking Dead: The Final Season, Injustice 2 and many others.

Let’s try to understand the pros and cons of Unreal Engine.

Pros:

• Immersive Graphics: Unreal Engine is mainly known for its advanced and immersive graphics capabilities and ability to create realistic game environments and game characters.
• Blueprint System: Unreal Engine offers a Blueprint system, a visual scripting tool for developers to create game logic easily without writing any code.
• Robust Community Support: Unreal Engine, the Engine behind hundreds of popular games, offers robust community support. You have extensive resources and development support available for any issues and needs.
• Modular Tooling: Unreal Engine offers modular tooling help to help game projects with a wide range of built-in tools and features. Game developers can find level editors, asset browsers, animation systems and many more.
• Blueprint Marketplace: The Engine also offers a standalone Blueprint Marketplace from where developers can get an array of pre-built assets and game development tools.

Cons:

• Steep Learning Curve: Unreal Engine is extremely difficult to learn, especially for game developers who are new and not familiar with the intricacies of game development. The advanced features and development tools require significant time to master.
• Performance Issues: Unreal Engine consumes many memories and needs high-end hardware, so games needing a high frame rate can encounter issues. Similar problems may occur with developers working on low-end computers.
• Cross-platform Support is not Good: Though Unreal Engine supports various platforms; it does not deliver as sound cross-platform development output as its native counterparts.
• Lack of 2D Capabilities: Unreal Engine is known for mainly 3D graphic capabilities and lacks 2D graphics features. It is possible to use the Engine for 2D games, but it does not reflect its best abilities.

Unity vs Unreal: Key Differences

As we have explained, Unity and Unreal Engine are powerful and well-equipped game engines for building video games and immersive gaming experiences. Though they have few similarities, some crucial differences between these two engines make their loyal audiences, core strengths and value propositions.

Let’s look at the core differences between Unity and Unreal Engine.

• Programming Language Support: Unity uses C# as the primary coding language, while Unreal Engine uses C++. This means developers with any of these skills will choose any of these frameworks for game development.
• Learning Curve: Both engines stand similarly here as they have a steep learning curve. Even then, Unity is comparatively easier to learn compared to Unreal Engine. The visual scripting system and easy interface of Unity make it popular.
• 2D Capabilities: Unity is used for both 2D and 3D game projects. On the other hand, Unreal Engine is not fully optimized for 2D graphics. Hence the latter is more difficult for building 2D games.
• Graphics Capabilities: Unreal Engine is known for its true-to-life graphics capabilities and can deliver high-quality, realistic game environments and characters. Unity is equally capable of creating impressive graphics, but in comparison, it goes behind Unreal Engine for graphics output.
• Community Support: Both game engines come with large communities of game developers. Here Unity has an edge as it has a bigger user base and resources that game developers can access.

Unreal vs Unity: Pricing and Cost

As we have explained, both Unity and Unreal, as two leading game engines, differ in many respects despite their immersive virtual reality capabilities, modular architecture, cross-platform support and extensive community. But there is a significant area of difference: pricing and the development cost.

Unity comes with a free version known as Unity Personal. This free version offers basic features and is ideal for smaller game app projects. We have Unity Plus and Unity Pro for fully-fledged and large projects requiring advanced features. These versions require a monthly and a yearly subscription fee, respectively.

Unreal, however, is free for all personal and educational uses. But for commercial game app projects, the developers must pay a 5% royalty fee whenever the gross earnings from the game crosses over $1 million in a year.

So, regarding overall game development cost, there is little scope for a direct comparison between Unity and Unreal. Though it entirely depends on the specific needs of the game app project. Unity’s pricing structure seems more affordable, and Unreal’s royalty model can be more suitable for larger game projects.

Ending Notes

Ultimately, choosing between Unity and Unreal Engine for your game project will depend on the specific attributes of the game. While the Unity vs Unreal comparison will continue, one needs to choose any of them based on the type of game they need to build. A game engine is chosen based on what gaming experience you want to deliver. Cost and other factors only come later. How well you utilize the potential of these two engines for your game app project will be crucial.
