The Beginning Game Programming with C# course is all about learning how to develop video games using the C# programming language. Why use C# instead of C++, Java, ActionScript, or some other programming language you may have heard of? First, using C# lets us use the open-source MonoGame framework, which help us quickly develop games for Windows, Android, iOS, Mac OS X, and others. Second, the Unity game engine is very popular with indie game developers, and C# is one of the programming languages you can use in the Unity environment. And finally, C# is a really good language for learning how to program.
