I think, knowing technical aspects will not be superfluous. All projects i stated with this engine are using advanced features. Maybe, that's why games look so. Thank you so much for feedback!
I am not saying you don't use advanced techniques, don't get me wrong. I just mean you don't need to write your own game engine or custom shader code to get a unique look. You use a restrictive engine and still get a very unique look. It is impressive :)
