If all your background in computers is being an NOC technician.
Only questions that race through my head are, do you have an IT degree or a CS degree.
Game development is indeed a very complex process. Yes we have modern software that makes it more simple, but you will indeed come across errors in your dev process that without the appropriate background you will not know how to solve this.
If this is your wish. Take the time now to increase your background. Don't throw yourself into the industry without careful planning and practice.
Yes a company may hire you, but if your not already skilled at doing the job. Expect to be fetching coffee and taking out the trash.
Game development in particular when it comes to software management is so competitive that your better off starting your career doing other software engineering jobs.
Best way to go about getting your foot in the door is to get some sort of college background in computer science, if you already have an IT degree, take extra classes on your own as non-degree that are cs related and ask questions. Then work on side projects and build a portfolio.
Yea there aren't really tutorials on the internet for this stuff. It is because the task is very challenging and not so easy to put together in one place for people to understand easily. The individuals who can do such a thing are too busy working to be sitting down creating tutorials.
Just pick a language, any language. Learn programming.
Then build a portofolio and train your skills. Yes a game dev company will train you. But like i stated earlier. If your not always qualified to do the job before your hired. Your role on the projects will be very limited.
