While IL2CPP transforms C# into C++ already, it generates a lot of overhead. There are many [surprises](http://jacksondunstan.com/articles/3916) if you read through the generated C++. For example, there's overhead for any function using a static variable and an extra two pointers are stored at the beginning of every class. The same goes for all sorts of features such as `sizeof()`, mandatory null checks, and so forth. Instead, you could write C++ directly and not need to work around IL2CPP.

## Industry Standard Language

C++ is the standard language for video games as well as many other fields. By programming in C++ you can more easily transfer your skills and code to and from non-Unity projects. For example, you can avoid lock-in by using the same language (C++) that you'd use in the Unreal or Lumberyard engines.
