16 Recommended 3D Game Engines

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

"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." - ( 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 2

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 3

Unreal Engine 4

Unreal Engine 4 is the new version of one of the most widely used game engines out there; the Unreal Engine. It features new interface, new material pipeline of physically-based shaders, Blueprint visual scripting, DirectX11 rendering, improved lighting and the list can go on. But you may want to check out all the features yourself.

Unreal Engine 4 is now offered as a free download. It did require a monthly subscription fee but that is no longer the case.

Unreal Engine 3

Unreal Engine 3 is the complete toolset to create your own games. It is a very widely used game engine in the industry. Unreal Engine is 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 Unreal Engine games go here: list of Unreal Engine games. Unreal Engine is one of my favorite engines to work with. UDK is a free educational version of the engine, with commercial license available if you want to take your project further and sell it.

CryEngine 3

CryEngine 3 has been used in games such as Crysis 2, Crysis 3 and Sniper: Ghost Warrior 2. Just like Unreal Engine 3, CryEngine 3 is the complete toolset for game development. CryEngine 3 has been used as a benchmark for visual graphics for some time and it continues to push the limit what games are capable of. One of CryEngine's features is its ability to produce huge beautiful, highly detailed landscapes.

CryEngine 3 SDK is now on Steam and requires a monthly subscription service. You can also choose a full license but for independent game developers and hobbyist, Steam subscription will be enough.

You can still find a free version of CryEngine 3 SDK somewhere online. I believe the last free version was 3.5.8 but it is no longer being updated by Crytek. For new updates and new version of the game engine you will need to sign up for subscription service.

Free version of CryEngine 3 SDK is still available with all the necessary tools to start creation your own worlds or your own game.

Source Engine

Source Engine has been used very extensively in the modding community with hundreds if not thousands of mods available. Source Engine is a bit outdated, yet still very powerful. It has been used to create games such as Half Life 2 series, Counter-Strike: Source, Counter-Strike: Global Offensive, Left4Dead, Left4Dead 2, Portal 1 and 2. Each game has a huge community behind it with new content always being released. I love using Source Engine because of its games. You can get your hands on the engine by downloading any of Valve's released games on Steam. If you are interested in licensing Source for commercial project go here.

Eventually Source is going to get an update to Source 2 with unconfirmed and possible releases of Half-Life 3 and Left4Dead 3.

I myself can't wait for the day that happens.
