Best free game engines for developers in 2021

There are quite a few options when it comes to making fluent and responsive games. Developing can be made so much easier with the help of game engines. You don't have to code everything from scratch and you can jump right in with our worrying about the price tag.

We've been looking through game engines to see whichever works best, provides a responsive UI, has a fast learning curve and works on both Mac OS and Windows.

1. Unity 3D

Unity is a large game engine designed to make responsive games. Unity provides documentation on most topics and they have great customer support. With Unity developing is so much easier and you can start right away.

Pro's:

- Offers a free version

- Fast learning curve

- Fast shader creation with ShaderGraph

- Great visual effects creator (VFXGraph)

- Tons of free plugins and assets (Unity Asset Store)

- Comes with vusual studio community in the installer

- Supports most coding languages

- Can support 2D games

Con's:

- Need to install Unity Hub for Unity to work

- Need to create a Unity Account for a personal license

- Build times can be time consuming

2. Unreal Engine

When it comes to graphics and visual effects unreal engine is the way to go.

Pro's:

- Great options for visual effects

- Easy coding with code flows

- High graphics

- Has a asset store (Unreal Engine Marketplace)

Con's:

- Most low-end devices can't run the games and may be unresponsive

- Steep learning curve

- Build times can be time consuming

- Not a wide variety of platforms to support

We use Unity over Unreal Engine because not only can Unity create responsive but high graphics 3D games but it can also do the same with 2D games.
