What Level Editor and Game Engine Should You Use - (How to Choose)

What is a game engine?

"The core functionality typically provided by a game engine includes a rendering engine ("renderer") for 2D or 3D graphics, a physics engine or collision detection (and collision response), sound, scripting, animation, artificial intelligence, networking, streaming, memory management, threading, localization support, and a scene graph. The process of game development is often economized, in large part, by reusing/adapting the same game engine to create different games, or to make it easier to "port" games to multiple platforms." - (wikipedia.org/Game Engine)

Few examples of games and game engines used to create them are:

Games: Dota 2, Half Life 2 series, Counter-Strike: Source, Counter-Strike: Global Offensive, Left4Dead, Left4Dead 2, Portal 1 and 2
Game Engine: Source Engine

Game: Hitman Absolution
Game Engine: Glacier 2

Game: Battlefield: Bad Company 2, Battlefield 3, Need for Speed: The Run
Game Engine: FrostBite

Games: Mass Effect Series, Dishonored, Bioshock Infinite, Batman: Arkham Asylum and City and hundreds more
Game Engine: Unreal Engine

Game: Crysis 2 and 3
Game Engine: CryEngine

Not every game engine is available to download without paying for a license first. However there are many affordable, free, open source and non-commercial versions that you could work with and download right now.

In this blog post I will provide you with options and links to 3D game engines, their features and download page so you can make a better decision on which one is right for you.

Criteria used to include a 3D game engine in this list were:

  • Available to download
  • Affordable, free (easy access) or open source
  • I have used it myself and recommend

So, for those who are interested in going a bit further into game development, to explore new technologies to showcase your game environments in or just curious behind game engine technology; here are 22 suggestions for game engines you can get your hands on right now.

3D for 2D

Following list is for 3d game engines. Any 3D game engine can be used to create 2d games. Although using a 3d game engine to create a 2d game can often be excessive. If you are looking for recommended 2D game engines, see this post (Coming Soon.)

Unreal Engine 4

Company: Epic Games
Platforms: Windows, Mac OSX, iOS, Android, VR (including but not limited to SteamVR/HTC Vive, Morpheus, Oculus Rift and Gear VR), Linux, SteamOS, HTML5, PS4, Xbox One

Unreal Engine 4 is a complete suite of game development tools. From 2D mobile games to console to VR, UE4 provides you with everything you need to start, create and ship a game.

Epic regularly releases new versions which include updates, improved features, community contributions and bug fixes.

Once you ship your game or application, you pay Epic 5% of gross revenue after the first $3,000 per product per calendar quarter. See this FAQ for more info.

Note from WoLD: I use and recommend UE4 as the game engine of choice. See Unreal Engine 4 tutorials list here.

Unreal Engine 3

Company: Epic Games
Platforms: Windows, iOS, Mac OSX

Unreal Engine 3 is the complete toolset to create your own games. Although there is a newer Unreal Engine 4 version out. It is still a very versatile and has been used to create many triple A games such as: Batman: Arkham City, Gears of War Series, Borderlands Series. For a full list of games that used Unreal Engine 3 go here.

UDK is no longer being updated or supported but it was one of my favorite engines to work with before Unreal Engine 4 came out.

There are a lot of tutorials out there for UDK and you can still get your hands on the game engine. Although it is very likely you will go with the newer Unreal Engine 4.

CryEngine V

Company: Crytek
Platforms: Windows, Linux, PlayStation 4, Xbox One, Oculus Rift, HTC Vive, Open-Source VR and PlayStation VR

Crytek completely revamped CryEngine in 2016.

Originally it was called CryEngine 3 SDK  and now it is CryEngine V.

Cryengine V has now become available as a "pay what you want" service, allowing the user to set their own price. If you like the service CryEngine provides then you can contribute to its ongoing development. That is pretty amazing deal.

CryEngine features include full engine source code, fully commercialization, 100% royalty-free, access to all supported platforms and ready for VR development.

CryEngine has been used in games such as Crysis 2, Crysis 3, Evolve, Sniper: Ghost Warrior 2 and 3, and Homefront: The Revolution.

Just like Unreal Engine 4, CryEngine is the complete toolset for game development. It engine has been used as a benchmark for visual graphics for some time and it continues to push the limit what games are capable of.
