Okay, let's break it down: I don't know if I can consider it a course as "self-learning," but it doesn't give me any diploma, certificate, or anything like that. I study at a "school" called Orango, but again, it's nothing like a bachelor's degree, for example. My country doesn't have many incentives in the game development field, and it also doesn't have much tradition in the area, although it already has some world-renowned indie developers. Because of this, the only university that actually offers this area of study is more than 700km away from me, and I can't attend right now, I intend to, but I can't now.
And I understood what you meant. My fear is always the beginning, how it starts, and even though I haven't actually started a degree in the field yet, I wanted to try to take my first steps, try to build a portfolio, etc., etc. And the fear of what the beginning is like led to the suggestion for the post. Thank you for your comment, it was very enlightening.
