Godot is a great example. The vast majority of the code you write is single function, callback style procedures. Rarely are you creating a hierarchy of class interfaces or dealing with a large multifaceted infrastructure. You are writing what can be done in pretty mundane python.

Rather, C# is there to grab the Unity community and they only really use it because idiomatic Unity may have bigger projects creating engines. C# still follows the HelloWorld complexity property of programing languages.
