Thank you for your encouragement, opinions and experiences.
It is true that modern engines have a visual editor of "scenes", which you can modify in real time, like a 3D modeling editor.
I know Unity, from its beta version for 2010, I was shocked, because of the complicated interface and not knowing where to start, in only english GUI.
It is a very powerful engine and slow in response time and load, requires a medium-high hardware.
GameMaker is very similar, also with scene editor and a similar GUI.
About 2006 I had a funny experience with the RPG Maker, I overdone it to the maximum and I realized that it is for children jajaja, you do not learn a programming language and besides being very limited jajaja.
I want to help make known that AppGameKit exists and it is good for those who love to program exclusively.
Here in Spain, (I am Spanish) I want to spread that there are other options!
Not always Unity / Unreal, Godot, Gamemaker ... That's fashion!
I am very interested in DarkBasic, also with AppGameKit I try to use multiplatform to the maximum that I can! Windows, Linux, Android ...
I have a RaspberryPi3, it's a love!
