Hi, if you check my profile https://steemit.com/utopian-io/@sp33dy, I've provided lots of different tutorials, market Beginner, Competent and Expert. There's one that shows you how to install Godot (which is really quite simple and FAST). There's another that shows you how to get one of the sample 3D games up and running. Then there's a bunch that have gradually been building a 'Space Invaders' clone. What you are looking at here is a 'Competent' developer, i.e. one that knows their way around the GUI (which you would quickly learn from the others I mention). The advice I have is, get it installed and try it! Seriously, it won't take you long.
