If you are an advanced programmer, should you use c# instead? I understand it is good for performance but I'm thinking will I save any time using it if I would benefit from more advanced features like nullable? Or would the increase in development speed from gdscript make extra language feature negligible? I do however like static typing to not have cyclic dependance so, for me, gdscript, although it isn't perfect it is a great because its simple enough and enables you to get a lot done quickly!
Speaking of gdscript, does anybody know of any good tools I can use to increase development speed? Give your reason why it helps!
