Gaming engines were developed with a mind to allow the game developers to provide all the tools in one place which would result in fast pace development of the game. Few Advantages of using game engines:-

  1. Code Recycling:- As the game complexity increases, the reuse of code becomes a big advantage for the developers as it not only saves the developer’s time but also reduces complexity.
  2. Game engines come with rendering and physics engines, where you can see your development in real-time, It blends any 2D or 3D input format which compatible with any platform.
  3. It also comes with a sound engine where you can easily design and control the effect, integrating easily at any stage of game development.
  4. It also supports networking that allows multi-player and lets you connect with social media to enjoy playing games with other users.
  5. One of the key features of developing a game on the game engine is artificial intelligence, It provides a significant impact on the development process and games’ logic.

Little History of Unreal Engine

Before moving forward on advantages and how powerful the Unreal gaming engine is, let us first try to see how this gaming engine came and involved into this big popular gaming engine giant.

The first version of unreal gaming was developed by Tim Sweeney, who is also the founder of Epic Games too. At first, the engine entirely relied on CPU power for all graphics calculations a.k.a software rendering. According to him, the hardest part was program rendering as he had to rewrite core algorithms several times during game development.

In 2002, the second version debuted with an American Army, a multiplayer shooter simulation game developed by US Army for their recurrent process. The rendering process was improved significantly and it also added new toolsets. The new engine boosted the game quality 100 times with highly detailed graphics as its rendering power got increased.

The third version’s screenshot of Unreal engine was showcased in July 2004, which was based on first-generation but with more advanced features. The parts of the game were fairly visible to gamers like rendering, sound, and physics system. The Epic Games released a free version of Unreal Engine SDK, known as Unreal Development kit which was available for the general public.

Mark Rein, the vice president of Epic Games, 2005 revealed Unreal Engine 4 which was in development period for two years. It was based on subscription models, developers had to pay 19$ to access the full version of the engine. Later, Epic Games announced a free version for schools and universities, including personal copies for the students who were enrolled in game development, computer science, art, architecture, and visualization programs.

This move by Epic games really boosted the popularity as it made the engine made more affordable and if the students were started their game development using their free version, then they will surely use it at a professional level as they were already got habituated to using Unreal engine, and this exactly happened and Unreal engine grew 10 times.

Unreal Engine the most popular engine

Blueprints visual scripting language

Blueprints a visual scripting language is a key differentiates which makes it different from the other engines. It is used as an alternative to a C++ native programming language, It helps for rapid prototyping without having good knowledge of the programming language.


The best part of the Unreal Engine is it is open-source software, any developer can download unreal engine source code easily and it promotes developers to contribute and refine it.

Market Place

Unreal Engine has a big marketplace which is a digital storefront for developers which allows developers to develop various assets like graphic art, models, sounds, environments, and code prototypes that can be purchased and sold.

High Graphics Imaging

Unreal Engine is great for making high-budget games where you need to achieve the ultimate graphics quality. When it comes to graphic quality, Unreal Engine really takes lead, and the engine’s rendering and realistic effect helps users to create a real-life environment that engages users.


Games developed on the Unreal engine can be easily exported to any platform like ios, android, consoles, and also on some HTML5 pages. It is also supported by Windows, macOS, and Linux.


Unreal Engine uses very less memory and resources which enables developers to render high graphic models without being worried about over-clocking of CPU and the engine also comes with a lot of tools for game optimization.
