Unity vs Unreal: Which Game Engine Should You Choose?

I’m going to explore the debate of Unity vs Unreal Engine in 2024. It's a popular topic, and I'm excited to weigh in with some facts. 

In a nutshell, they’re software development environments with pre-built gaming components that you and I can use to build video games. Great, but why the debate over Unity vs Unreal Engine? Well, while they both offer physics engines, 2D and 3D rendering, AI, and more, there are some major differences.

So whether you’re an experienced pro who’s trying to navigate the minefield of Unity vs Unreal Engine, or a newbie that’s weighing up where to get started, this article is for you!

Is Unreal Better Than Unity?

If you’re new to game development, you might be thinking to yourself, what do you mean by Unity vs Unreal Engine? And why does it matter?  It's an age-old battle! Like choosing between driving a new car or taking a trip to a coffee shop; it depends on what you're looking for.

To my mind, Unreal Engine is like the high-end sports car of the gaming world. It boasts stunning graphics and a Hollywood-level rendering engine. So if your game's all about eye candy and jaw-dropping visuals, Unreal might be your best choice.

On the other hand, I like to think of Unity as the friendly neighborhood cafe. It's super friendly for beginners, and it's endlessly versitle. Those factors make it an excellent option for indie games or prototypes.

But still, is Unreal better than Unity?

That's like asking if pizza is better than tacos. They're both awesome, just in different ways!

Ultimately, it depends on your project, team, and personal style.

One thing we have to mention is the latest news that Unity will be spicing things up by introducing a new fee system.

From Unity, "The Unity Runtime Fee will only apply to certain games created with Unity Pro and Unity Enterprise." It doesn't apply to their free tools (or the Unity Plus plan). 

That said, let's take a much deeper dive into these two game engines to help you choose the best for your project.

Let's kick things off with a nice head-to-head!

Whether you're new to game development or looking for quick answers, I've put this table together to give you the skinny on both options before we dive deeper.

What is Unity?

Unity is a cross-platform game engine developed by Unity Technologies and released at Apple’s 2005 World Developer Conference (WDC).

Unity provides support for over 25 gaming platforms, including PCs (Windows, macOS, Linux), consoles (Xbox, PlayStation, etc.), mobile devices, and several virtual reality (VR) platforms like PlayStation VR and Oculus Rift, to name a few.

When it comes to actual coding, Unity relies on one of the best languages for game development in the form of C#.

Many users have adopted the Unity game engine as it allows them to create and experience 2D, 3D, and VR games. It has also been adopted by a variety of industries outside of gaming, including film animation and visual effects, automotive, architecture, engineering, and construction.

If you're brand new to coding and Unity, the good news is that there are lots of great Unity courses and tutorials you can take to upskill in no time at all.

Something that will be changing with Unity in January 2024 is the introduction of a new fee system.

The TL-DR here is that Unity developers will be hit with a 20c charge per download once their game makes more than $200,000 and exceeds 200,000 installs.

Similarities Between Unity and Unreal

Despite their rivalry, Unity and Unreal do offer some similar tools and features for game design and development, including:

  • The capability to produce AAA-quality graphics along with bridges for most industry-standard software
  • An extensive toolbox including terrain and material editors, animation, physics simulation, and VR Support, among others

That said, it's fair to say that there are some fairly significant differences too! Let's take a look at these now.

Differences Between Unity and Unreal

Differences Between Unity and Unreal

Some of the main differences you should bear in mind when deciding between Unreal Engine or Unity include:

  1. Source Code: Unreal Engine provides full access to the source code, while Unity offers read-only access
  2. Release Date: Unreal Engine made its debut in 1998, while Unity was announced and released in 2005
  3. Languages: Unreal Engine uses C++ and Unity uses C#, which is often considered faster to learn and more suitable for beginner game development than C++
  4. Community: Both engines have a huge community of active users, but Unity currently makes up nearly 50% of the market share compared to 13% for Unreal
  5. Documentation: Both offer detailed documentation explaining their tools and features
  6. Asset Store: Asset stores allow users to download ‘mods’ like new textures or props for their games. Unreal offers around 16,000 assets, while Unity offers over 65,000 assets
  7. Graphics: Both tools produce excellent graphics, but Unreal Engine is to go-to for the highest quality graphics and environmental details
  8. Rendering: Unreal supports faster rendering than Unity, which can speed up post-processing and game development
  9. Pricing: Unreal Engine is completely free, but a royalty system exists for revenues above a certain threshold. Unity is also free, and they offer a paid version for professional studios (based on the number of licenses), although they will be adding a new royalty system in January 2024.

Community Feedback

Michael Robert on Unity

I'm always checking in with our readers to find out what they think. In this case, we heard from a Michael Robert. He's a cybersecurity specialist and tech expert with a Boston University Bachelor's degree in cyber/Computer Forensics and Counterterrorism. He's also a senior technical contributor at GTA Boom

For him, the answer is Unity.

"Unity is better for beginners just starting out with game development. Its interface is very easy to use so you won't feel overwhelmed. C# is also easier to learn than C++, which Unreal Engine uses.

Unity also makes 2D games simpler than 3D games. If you want to make a 2D side scroller or puzzle game, Unity will prepare you better."

Wrapping Up - Unreal or Unity?

So there you have it! We’ve taken a deep dive into the hotly contested race of Unity vs Unreal Engine.

As you’ve probably gathered if you’ve made it this far, the answer to the debate of Unity vs Unreal Engine is not straightforward! 

And in my opinion, it is hard to imagine modern game development without both of these incredible game engines. 

And sure, while both have pros and cons, the right choice ultimately depends on your project’s requirements and also your coding language preferences. 

When it comes to summarizing Unity vs Unreal Engine, I think it’s good to remember the following points.

With Unity, you get an engine that’s renowned for its huge user base and excellent support for 2D and 3D gaming. It’s also easier to learn for newer developers thank to C#.

And with Unreal Engine, this is awesome for building large and complex games due to its high-fidelity and photorealistic 3D graphics. 

But, you do need to know or be willing to learn C++, which might put off newer coders. Because of this, Unreal Engine might be better for experienced developers.

Regardless of where you land when assessing Unity vs Unreal Engine, either choice can lead to spectacular results, so have fun, and let us know in the comments below which you prefer.

Frequently Asked Questions

1. Unity vs. Unreal: What’s The Better Game Engine In 2024?
