If you are a programmer with a passion for game development or a computer science graduate who wants to become a Game Developer for the console, Android, or iOS device and looking for some excellent courses to start with, then you have come to the right place. In this article, I am going to share some of the best Game Development courses which are entirely free using Unity, Corona, and LibGDX, three of the most popular game engines for Programmers and Game Developers. While LibGDX is Java-based and Unity is C# based but probably the most popular game engine at this moment. Unity Game engine is both powerful and free, which makes it ideal to use for game development. If you don't know, Unity is the same software used to create Pokemon Go and many other best selling mobile games!
