The Unity 3D game engine comes with significant improvements in the learning area.
If you know nothing about Unity Editor and C # then this area has a simple and efficient introduction for new developers of this game engine.
For example , see the Creator Kit: Beginner Code.
You can start with John Lemon's Haunted Jaunt: 3D Beginner or with the Ruby's Adventure: 2D Beginner.
I am starting to see how deep and good these tutorials are and for me it was quick to follow them and use them.
This is an more advance learn step from Unity 3D using the Creator Kit: Beginner Code.
