What is a Game Engine?

A game engine / gaming engine is a software development program or environment used originally to develop video games. Now, a game engine can also be used for media and entertainment (including virtual effects), visualization (as with the development of digital twins), collaboration, and more. The features of a game engine may include animation tools, artificial intelligence, physics and collision engines, audio engines, and more.

What Are the Best Game Engines?

Unreal Engine and Unity are considered to be two of the best game engines.

Based on games released on Steam and Itch.io, Unreal and Unity are among the most popular game engines.

Unreal Engine is a commonly used gaming engine because it is:

• An open and advanced real-time 3D creation platform.
• Used to produce games in multiple genres.
• Integrated with key game development tools, including IDEs, graphics tools, and version control.

Unity is a commonly used gaming engine because it is:

• A cross-platform game engine, with support for over 25 platforms.
• A leading real-time 3D development platform.
• Integrated with key game development tools, including IDEs, graphics tools, and version control.

Unreal Engine and Unity are not the only top game engines.

The Top Game Engines

There are many game engines that you could use for game development for PC games, console games, and mobile games. Here's a list of the most popular game engines used today:

• Unreal Engine
• Unity
• Godot
• Amazon Game Engines
• CryEngine
• Your Own Game Engine

Unreal Engine

Unreal Engine is a top game engine developed by Epic Games since 1998. While teams may love Unreal Engine 4 (UE4), the release of Unreal Engine 5 has introduced some much-anticipated improvements and new features.

Unreal Engine is a well-documented and easy to use game engine. You can use it to develop any type of game — from console to mobile (including Android and iOS). It’s even used in industries beyond game development, including automotive.

This makes it a top game engine for beginners and experts alike. That’s why everyone from AAA game developers to indie studios uses Unreal Engine.

For example, Unreal Engine is used in Epic Games’ biggest games, including Fortnite: Save the World. It’s also been used by countless other studios for games like Mortal Kombat (mobile).

Which of the Most Popular Game Engines Does Gearbox Use?

Gearbox chose Unreal Engine as their game engine to build games like the iconic franchise Borderlands. Take a deep dive into their game development process in this webinar.

This makes it a top game engine, especially among cross-platform teams. You can use it to develop any type of game. It has a strong reputation for mobile game development on Android.

For example, Unity is used for mobile, PC, console, web, and AR/VR games. These include Cuphead and Rick and Morty: Virtual Rick-ality.

In addition, Helix Core features an integration with Unity. Together, they provide critical functionality to the game development process, helping teams develop great games.

If you would like to set up Helix Core with Unity, review this tutorial.

Amazon Game Engines

Amazon Lumberyard is a game engine developed by Amazon. Founded in 2016, the source code was originally licensed and reworked from CryEngine (see below).

Lumberyard is a free, cross-platform engine. But recently, Amazon has taken its game engine and transformed it into an open-source model. Open3D is the latest from Amazon. It builds on top of Lumberyard and creates a more modular approach to game development.

It’s an easy gaming engine to get started with, which makes it accessible to start-ups or indie studios, in addition to AAA game development studios.

Strengths

• Free for single-player games.
• Advanced support for VR.
• Integration with AWS for online multiplayer features.

For example, CryEngine is used in Hunt: Showdown from CryTek, as well as Kingdom Come: Deliverance from Warhorse Studios.

Strengths

• Default features are extensive.
• High-fidelity visuals are possible.
• Fast iteration process.
• Powerful Sandbox game editor.
• VR support.
• Easy to learn.

Weaknesses

• Steep learning curve for beginners.

Your Own Game Engine

Another top game engine used by studios is their own video game engine.

There are many studios that take game engine development into their own hands and make their own game engines. In most cases, studios that make their own game engines use them exclusively. In some cases, studios will use their own engines for some projects — and utilize other engines like Unreal for other projects.

For example, Nintendo uses its own video game engine. But Nintendo Switch supports Unreal Engine and Unity to allow third-party developers to port their games over.

Which Is the Best Game Engine?

Which is the best video game engine for your team? That depends on your studio and project.

In some cases, the best game engine for your team might be one of the top engines listed above:

• Unreal Engine
• Unity
• Godot
• Open3D Amazon 
• CryEngine

If after evaluating those tools, you're still asking yourself, "Which game engine should I use?" — the right game engine just might be one you build yourself.

How to Use the Best Game Engines with Version Control

Your game engine is an important part of your game development toolset. When picking a game engine, it should work seamlessly with your other game development tools, including version control. 

Version control is a staple of game development teams. And most game development teams — including 19 of the top 20 AAA game development studios — use Helix Core, version control from Perforce. 

Here is how to use game engines with Helix Core.

1. Download Your Game Engine

Go to your favorite game engine’s site and download it — if you have not already. 

For quick reference, here's where you can download the game engines mentioned earlier: 

• Download Unreal Engine
• Download Unity
• Godot
• Download Lumberyard
• Download CryEngine

2. Download Helix Core From Perforce

After getting your game engine setup, you will download Perforce Helix Core. 

If you are not using Helix Core yet, click here to get started. 

If you are already a Helix Core user, download the latest version of the: 

• Server (P4D)
• Visual Client (P4V)
• Command Line Client (P4)

3. Integrate Your Game Engine with Helix Core

Next, you will follow the steps listed in your game engine’s documentation for setting it up with Helix Core.

4. Use the Game Engine Editor (If You Are a Designer/Artist)

Most game engines have a built-in editor for designers and artists to work in. You can use the editor to work on assets — such as graphics — in the game engine. Since the game engine will be integrated with Helix Core, you will be able to check in assets into Helix Core — without leaving the editor.

5. Use an IDE (If You Are a Coder)

Most game engines integrate with IDEs, such as Microsoft Visual Studio. So does Helix Core. This means that if you are a coder, you can work on code in Visual Studio. You will be able to check your code into Helix Core — without leaving the IDE. Plus, designers and artists will have access to the same single source of truth, keeping everyone on the same page.
