Unity vs Unreal Engine: Which Game Engine Should You Choose?
Table of Contents
A Game engine or also known as game architecture or framework is a software development environment that is used by game developers to build interactive video games.
Developers construct games for consoles computers, and mobile devices using gaming engines as the engine are reusable components used to build the framework of the game.
Every average game engine enables developers to add general features like physics, input, rendering, scripting, collision detection AI and more without the need to code them.
Although there are several game engines out there but we shall discuss & weigh that two titans of the gaming industry unity and unreal engine. Let us read on.
What is Unity?
Announced and released in 2005 at Apple Inc’s WDC, Unity is a cross-platform game engine developed by Unity Technologies. The game engine supports more than 25 platforms including Windows, macOS, and also consoles and virtual reality platforms like PlayStation VR Xbox One, Oculus Rift, Daydream & many more. Unity game engine is adopted by many users as it gives the users ability to create games & experience them in 2D, 3D as well as in virtual reality. Outside of the game industry, it is also used by other industries such as film, automotive, architecture, engineering, and construction.

Similarities Between Unity and Unreal
- Both tools are capable of producing AAA-quality graphics and have great bridges between most of the industry-standard software.
- They both provide an extensive toolbox including terrain editor, animation, physics simulation, VR Support & etc.
Differences Between Unity and Unreal
- Definition: Unreal engine is a source available game engine, Unity is a cross-platform game engine.
- Invention: Unreal engine made its debut in 1998, Unity was announced and released in 2005.
- Languages: Unreal engine uses C++ and Unity uses C#. C# is considered suitable for game development than C++, So unity is faster.
- Community: Both engines have a huge community of active uses. However, Unity 3D has been accessible in unreal 4, and also it has more clients and hence user base.
- Documentation: Both offer good and detailed documentation explaining their tools and features. However, Udemy offers a wider range of Unity Courses.
- Asset Store: Asset store allows users to download mods like textures and props. Unity has a wide range of mods in comparison to unreal. Unreal has around 10000 assets while unity has 31000 assets.
- Graphics: Both tools have good graphics but the unreal engine is preferred over-unity because of its graphic quality.
- Source Code: Unreal engine has an open-source making the development process easier. Unity, on the other hand, does not provide open source code; however, it can be bought.
- Rendering: Unreal supports faster rendering making post-processing even faster. Rendering is slow in case of unity thus processing of projects is also slow.
- Pricing: Unreal Engine comes free of cost but you own royalties to them. Unity is available for free but the complete version can be upgraded with a one time fee of $1500 or $75/month.
