Unity vs. Unreal Engine 4 (2021) | Which One is for You?

Unity vs Unreal Engine 4
Unity3D vs. Unreal Engine

Game development has become common, and with free to program tools, anyone can build games. Unity and Unreal Engine are the two popular game development engines. Both are unique, and many developers have made many games through both.

The blog post covers the Unity vs. Unreal Engine battle. We will compare the essential tools and figure out which one is for you.

Quick Unity vs. Unreal Engine 4 comparison

If you are a beginner, I will recommend Unity because it has an easy-to-use interface and it supports C#, which is easier than C++. If you already have some coding experience and want to expand your knowledge and create 3D games, especially FPS and TPS, then Unreal Engine is for you. For the full comparison, follow the blog post.


The interface of both is a bit challenging. Still, if we are only comparing Unity and Unreal Engine, I will go with Unity because Unity is easier to use and navigate. Although you can also start with Unreal Engine 4 but compared to Unity 3D, you will have to practice a bit more to understand the software.

Winner: Both | Score: Unity: 1, Unreal Engine: 1


Unity is suitable for 2D and 3D game development, where Unreal Engine is more for 3D games. From the beginning, Unreal has been focusing more on graphics, which is the reason for amazing graphics quality on all platforms. Unity 3D is an all-rounder, but in graphics, it can’t win.

According to TairaGames, 3D games made in Unity is likely to drain the battery faster, while a 2D game made in Unity will drain the battery slower compared to Unreal Engine.

Winner: Unreal Engine | Score: Unity: 1, Unreal Engine: 2

Unity3D vs. Unreal Eninge 4 | Platforms

Unity supports over 25 platforms, while Unreal Engine 4 supports less than 20 platforms. Both are cross-platform, which means you only have to build the application once and deploy it to multiple platforms. Both are available on Windows, Mac, and Linux.

Winner: Unity3D | Score: Unity: 3, Unreal Engine: 3

Supported languages


One of the essential Unity vs. Unreal Engine 4 comparison sections. After everything, graphics and programming languages are the ones that impact significantly.

Both game engines offer non-programming game development using blueprints. Unreal Engine calls it the Blueprints, while Unity calls it Visual Scripting. Unreal’s blueprints have been here for a long time, but the Visual Scripting in Unity is a new feature starting release 2019.2. With tools, you can develop games without knowing to code.


Regarding the programming languages, Unity supports C# as well as JavaScript, while Unreal Engine supports C++. Compared to C++, C# is more comfortable to learn. C++ is a great programming language, but dealing with pointers and memory allocation is not a beginner’s game.

JavaScript on Unity also makes it easier for new developers to learn to code. Want to learn more about C# and C++? Read the comparison here.

Unity offers an Asset Store where developers can look around and buy the assets. Asset Store provides free and paid access to graphics, images, animations, materials, sound, full projects, etc., from other publishers. Unreal Engine also offers Marketplace where developers can buy the stuff. You can find assets like 2D tools, animations, characters, environments, FX, etc.

Both are available for free; however, there’s a certain point where you have to pay to continue earning money. With Unity, if your revenue is over $100,000 annually, then you must purchase the Unity Personal plan. There are three more upper hand premium plans with great benefits and an extended earning limit.

With Unreal Engine 4, if you make over $3000 per quarter per game, you will have to pay 5% royalty to Epic Games. There are no restrictions on the platforms as well as on the number of games you publish.

Which one is for you

For a new person who is starting to learn to code and build games, I will recommend Unity. A programmer who already has some knowledge of game development and wants to try something advance and build 3D games than Unreal Engine is a final choice.

Wrap Up

Let’s see the results from the comparison: Unity: 5, Unreal Engine: 5. Both work fine, and it’s entirely up to you, whichever you select. I hope the comparison of Unity vs Unreal Engine helped. Thanks for reading, and please let me know if you have any comments or suggestions.

  1. Sorry, but Unity’s asset store is not a plus. Some assets are coded so differently that they will not work with each other at all.
    UE4 market is pricey, but their coding structure is very strict in nature meaning that almost all packages will work, even overlapping ones.

    1. Well, you are right regarding Unity’s asset store limitations and about Unreal Engine 4. Both marketplaces have pros and cons. I kept the score as a tie because both have a marketplace.

    2. Really? How so? The problems can be, potentially, namespace clashes or order of execution mess-ups (as in you need your camera movement to run after everything else but someone set up their own script to run after even that. Both are easy fixes and really not that common.

  2. An interesting opinion, though it feels a bit dated.

    Interface – yeah, that’s true, Unity is easier to find your way in. It’s also easier to write extensions for it and the whole experience is just lighter. Unity editor seems to be able to run on a potato and UE4 needs a decent rig to run.

    Graphics – errrr no. Both Unity and Unreal are 3D engines. You make your 2D game in a 3D environment in both engines, and while Unity does come with a 2D physics engine you’re working in a 3D environment no matter what. As for better graphics, that has nothing to do with the engine, it has everything to do with the artists working on the games. While Unity has its fair share of games with poor graphics Unreal is starting to rival it there, too, since small teams are adopting Unreal quite a bit now. There is no technical reasons for not being able to get similar results in both engines, the big difference is that UE4 seems to turn everything including post processing on by default and Unity doesn’t. It still has the same tools and you can set up everything pretty much the same as long as you know what you’re doing. And while the new HDRP is still in preview it should be production ready in a couple of months, allowing you to do all the really expensive graphics things like insane amount of metered lights, subsurface scattering etc.

    As far as draining the battery goes – this is another thing that has more to do with the developers than the game itself. I recently played a few Unreal Engine 4 games
    that had less than impressive graphics. Of course this is all a matter of taste, but no spectacular visuals, no advanced graphics features or anything, but still it made the graphics card cooler noticeably loud, something that doesn’t happen with games with comparable, even better graphics. So I’d say it’s simply developers not optimizing their assets and using up CPU and GPU cycles on things that don’t matter.

    Pricing – yeah, completely true.

    Stores – yeah, both have asset stores. The Unity Asset store has more free things that are cool for prototyping, but store assets should be used sparingly anyway, there’s too many asset flips out there as it is.

    Supported languages – C# being easier than C++? Yeah, that’s kinda true. C++ allows you to do a lot of crazy stuff and you handle memory manually in C++. In theory. Except that it’s 2019 and there’s smart pointers. And, of course, because UE4 devs decided to use C++ for scripting their game engine they invented a whole bunch of crazy preprocessor directives that essentially turn C++ into C#. They manage the memory for you, they even have a crazy directive that turns a struct into a plain old data type like in C#. So again, pretty much the same thing, except that with Unity and C# if you google something you need in the language StackOverflow is likely to be of help. UE4 though… oh well, you have the documentation.

    Unity technically does support JavaScript (technically UnityScript), but they’ve been trying to get rid of it for ages now and many new API features are not available through UnityScript.

    Blueprints and visual coding – you can make a game without even knowing how to code – that’s just crazy. I don’t think you can. If you don’t understand the principles behind the code you’re not going to be able to code up anything, either by writing down code or by connecting nodes in a graph.

    Supported platforms – “you only have to build the application once and easily deploy to multiple platforms” – for someone who’s familiar with development of applications a build is the process of creating an executable application from code. When building a simple application you compile individual compilation units and then link them into an executable. Neither Unity nor Unreal Engine 4 will allow you to build just once for more than one platform. You have to build the game for each of the platforms you wish to target. It is often as simple as just flipping a build menu setting, but these are not platform agnostic applications, the build process just allows you to create correct binaries for each targetted platform, all from the comfort of the game engine.

    In any case, I’d say it’s all down to the developers rather than the engines. If you can make spectacular 3D graphics and are capable of coding up everything that needs coding up in a game then you can have a beautiful game in any engine. If you’re after performance then both Unity and Unreal will let you do that (Unity even lets you transpile C# to C++ now for release builds), but you will have to put in the work.

    1. Thanks, Andrej for all the points. Your comment provides a lot of information and focuses on some of the primary key differences. I’ll update the article in the coming days and add your name as a contributor. Thanks, again for all the words.

      Kind regards,


      1. I found Andrej’s comment to be incredibly helpful, so thank you for your article and the chance for someone like Andrej to comment on with personal knowledge.

        One thing i would like to say, as an old gamer thats trying to figure out their place in game dev, would be directly pointing at something Andrej hit on slightly. The graphics and type of games made in either engine. Thinking back to “Best FPS Game” from when i was growing up, and most people i believe really, Cryengine was the engine for FPS games. At least, we looked at Crysis as being the penacile of FPS gaming/quality. Now days there are a lot of really beautiful FPS games out there. You outlined some of them in your “created games” section.

        Getting to what i was wanting to point at, is that Unity has really moved up in what it can do, from what i can tell anyway. For instance, the game Escape From Tarkov. It is a very beautiful game, amazing graphics, physics and mechanics that are on point, as well as sound design that i havent really seen in many other games. I was corrected one day when talking about what engine it was in, as i assumed it was Unreal4, its Unity, in fact it wasnt even in Unity 2019, it was in an older build. I think EFT really shows off what Unity can do, and even by a smaller development company at that. That only puts Unity and Unreal that much closer together. I really feel like when it really comes down to it, the question isnt what environment you wish to develop in, but what language you feel the most comfortable with learning, or already know.

        In reality, looking from the outside, as someone with minor coding, level design and 3d graphics, I would be more drawn to Unity, as C# is “easier”. I would still need to learn everything else for Unreal, as well as learn C++ in depth, a much harder challenge.

          Thanks for the kind words. You are absolutely right. Both engines are capable of creating anything, but it comes to the level of programmer. At university, I found that C# is easier than C++, which is the reason for recommending Unity over Unreal for beginners.
