Before 2005, developing the 2D and 3D game apps for different platforms was quite a task as mobile game development for various platforms involves a lot of time, effort, and dollars. But, the launch of the Unity engine at Apple’s Worldwide Developers Conference turned the table upside down.

The powerful cross-platform engine enabled the game app development for 27 platforms and distinct devices in a user-friendly development environment. It provides a wealth of resources such as intuitive tools, ready-made assets, clear documentation, tutorials, and an online community free to create amazing 3D content in the games.

Rendering, Scripting, asset tracking, and physics are some of the features of Unity game development that reduce the time and cost of game development and offer flexibility to deploy projects on multiple platforms. The benefits have stacked up the Unity engine on the top of the cross-platform game development ladder.

According to a survey, “The Unity 3D engine has 45 % of Global Game Engine market share and preferred by 47% Game developers as the primary development tool.”

It’s awesome. But, the engine has some shortcomings as well, which makes the developers reluctant to use the engine for the next-Gen game app development.

Let’s take a glance towards the advantages and disadvantages which help you decide whether the engine works for the game development or not:


1) Platform support

The engine is highly preferred for its extended support to 27 platforms. The app developed and deployed can be easily shared between PC, web, and mobile platforms. Besides, the agile methodology enables speedy prototyping and constant releases, which in turn speed up the game development.

2) IDE

The text editor is provided by IDE to write the code, but sometimes a distinct code editor is also used by the developers to alleviate confusion. Additionally, the integrated development editor supports JavaScript and C# for scripting and also offers notable features that are ideal for game development.

3) Graphics

The high-quality audio and visual effects are supported by the engine that eases the game development. The visuals are adaptable on every screen and device without any distortion or compromise with the image quality.

4) Documentation

It’s a must-have. The novice developers need the easy-to-understand documentation that’s provided in detail by the Unity engine. The detailed documentation includes an explanation of every small topic.

5) Debugging

The debugging and tweaking is amazingly easier with Unity game development because all the game variables are displayed during gameplay, which in turn allows the developers to debug the process at runtime.


1) Graphics

Not to say, but the engine lags behind from a graphical point of view. It does not offer an array of tools to create stupendous graphics as opposed to other game development engines.

2) Physics

In the Unity 5 engine, the built-in support for the PhysX physics engine has some performance issues and lacks some important functionalities which need to be added to craft the excellent game app.

3) License cost

The developers need to have licenses for the best graphics, deployment, and performance improvements. These licenses are expensive to purchase. Moreover, the use of rendering, buffer support, stencil support, and pretty more features scale up the development costs due to expensive licenses.

4) Source code

The code is stable in Unity as opposed to other engines and packed with a great architecture that improves the game app performance. But, the unavailability of the source code makes finding, addressing, and fixing the performance issues difficult.

5) Memory hogging

The game developed leveraging the Unity engine consumes more memory, which in turn creates OOM errors and debugging issues in the apps.

The last word

In the game app development realm, the mobile game development company considers the Unity 3D engine on the top and rate it high for game development. The improved versions of Unity 3D have continuously upgraded the engine and fixed the issues. But, as every coin has two faces, the engine also has some downsides and benefits.

Now, you are familiar with the Unity engine in total. What’s your take? Do you find the engine the best fit for the next game app development? Do share your views in the comments below.
