Unity vs Unreal Engine_ The Battle of The Gaming Engines

A game engine is the most essential component when it comes to building or developing a game because it is the game engine that brings the in-game characters to life. Not only that, but it also helps in building the scenes, animation, graphics, and characters around the game. 

For game developers, the game engine works like an IDE or Integrated Development Environment that provides them with pre-built standard tools and various software components necessary for creating the game.

The work of a game engine is to simplify the complex task of game development while giving an abstract layer to the developers. This way the developers can freely use the tool to develop their games while the game engine does the heavy task in the background. Game developers mainly utilize the game engines to produce games for PCs, consoles, mobile devices, etc.

If you are someone who wants to pursue your career in game development then you should be aware of the two most popular game engines used by seasoned game developers, namely Unity 3D and Unreal Engine. In this article, we will know more about Unity 3D and Unreal Engine as game engines and compare them with each other.

Unity vs Unreal Engine


Current Status of the Global Gaming Market

In the year 2020, the global gaming market was worth 203.13 billion US dollars. The COVID-19 pandemic had a massive impact on the entire gaming industry, which was shocking for the game developers and gaming studios. According to different market research agencies and multiple reports, the worldwide gaming market showcased a massive growth of 38.24 percent in 2020. 

As per the previous market prediction, the growth of the gaming industry was projected at 229.16 billion dollars in 2021 to 545.98 billion dollars in 2028 with a CAGR of 13.20 percent during the entire period. A large number of people all over the world have been inclining toward games as their primary source of entertainment.

Through video games, people are releasing their stress and it also provides the gamers with a sense of joy as well as the experience of working together in a team. Moreover, studies have proven that you can calm down playful kids and simultaneously entertain adults with the help of video games.

Game Engine Market

Game engines work as the major software for developing a video or computer game. There are multiple important functions that you can get from a game engine such as scripting, artificial intelligence, animation, physics engine, sounds, memory management, collision detection, etc. Game engines are the medium through which you can not only have full command over a game but at the same time, you can have total control over the game settings.

In the year 2017, the global game engine market was worth 1717.2 million dollars and by 2026 it is expected to reach 4186.9 million dollars, which showcases a CAGR of 10.6 percent between the same period. 

The implementation of Augmented Reality (AR) and Virtual Reality (VR) is going to have a huge impact on the global gaming market. We can already see the impact of AR and VR in Pokémon Go. Niantic, the company behind the game, has successfully made billions of dollars in revenue by implementing the same technology in the game.

What is Unity 3D?

Unity 3D is a powerful IDE and game engine platform for developers. Unity has multiplied prebuilt- features that can help in making a game work. These built-in features include 3D rendering, physics, collision detection, etc. If we look through a developer’s eye then we won’t have to manually build everything from scratch while developing or creating a game. While starting a new project you won’t have to apply new physics laws by separately calculating their movement to decrease the level of surrealism in the game.

Moreover, the reason Unity is considering among the best game engines by developers is because of its asset store. It is a community-based section in the game engine platform where the game developers can upload their work and the whole community can utilize the same. 

For example, if you need a beautiful fire effect but don’t have enough time to build everything from scratch, in Unity 3D you will be easily able to find the fire effect you are searching for directly from the asset store. While working on Unity, the game developers can freely concentrate on their projects while coding for the feature that is extremely unique to the game. Unity game development allows for building robust and scalable gaming applications.

Unity vs Unreal Engine


What is the Unreal Engine?

Unreal Engine, as its name suggests, is a game development engine that was developed in the year 1988 by the famous gaming studio Epic Games. Initially, the platform was a first-person shooter game but right now it is being utilized to create and develop games of different genres including Stealth, RPG (role-playing games), MMORPG (massively multiplayer online role-playing games), fighting games, etc.

The platform only supports C++ as its coding language and it is immensely popular among seasoned game developers and gaming studios. The basic development technique offered by Unreal Engine is extremely helpful for beginners and freshers in the game development industry. The tools available in Unreal Engine provide the users the license to develop and create their games.

Unreal Engine is counted among the best game engines and is famous for its easy customization, in addition to the tools readily available to create HD AAA games without a lot of effort. Most of the freshers in this industry utilize the Unreal Engine platform to initiate their career in the gaming industry and create a portfolio for presentation.

It has various unique mechanisms through which users can run the game on their own. Not to mention, the editors and systematic set of tools available on the platform can help the developers modify the properties of the game and create the necessary artwork. 

Unreal Engine has different parts including an online module, input, graphics engine, physics engine, gameplay framework, sound engine, etc. The editors available in the Unreal Engine are necessary to develop games on the platform.

Unreal engine games are widely available and are some of the most played ones in the world. 

Unique Characteristics of Unity 3D that Make it One of the Best Game Engines

Easy Access Unity Asset Store

The adage “Easier said than done” stands true for Unity 3D as no game development software at present offers its audience a fully inbuilt and easily accessible asset store. The Unity Asset Store makes it one of the most popular features among game developers due to its multiple pre-designed assets. 

Before this, who would have thought accessing 2D/3D animation renders, pre-designed 3D models, and gaming tutorials will be just one click away?  The Unity Asset Store is an ideal characteristic that enables developers and designers to purchase assets according to their upgraded requirements and design needs.

Multi-Platform Developers’ Game Engine

Unity 3D is a platform that enables developers to build multiple projects for multiple gaming devices including Console (PS4 or Xbox), PC, AR/VR experiences, and mobile devices. It is currently the only suitable integration game engine for gamers across all major platforms. Developers can both build and port their games from one gaming platform to another with great ease. 

The processes of rendering and transferring assets also function smoothly in Unity 3D. Particularly graphics rendering is one of the most exciting features in Unity. This is because other platforms have their personalized system settings but in Unity, rendering from other engines like Direct 3D, OpenGL, Adobe, etc. are the simplest.

Rich Variety of Online Tutorials

Gamers feel that one of the most helpful characteristics of Unity 3D is the repository of online tutorials and learning materials. This bulk of rich learning resources in Unity boasts well-documented processes, detailed steps, multilingual texts, and video forums that enable a comprehensive understanding of gaming concepts.
