Nope Prescott you make zero sense I am afraid.
Your assumption that you will magically become able to make games from scratch in Unreal with a handful of video tutorials is illogical to say the least.
This is nothing more than introduction, you will have to do it like the rest of us, sit down and practice a lot the skills you learn in these tutorials and then carry on the learning process by yourself.
You don’t need a mind that is not blank to make games, a mind that is blank will do just fine. I am coding for over 30 years now and 99% of the time I have no clue what I am doing because I am always doing or trying something new. I don’t see any value on doing things I am familiar with anyway, plus its no fun.
Last week I have been learning how to share memory between 2 processes made in different programming languages. That means I had to go very low level inside the OS kernel, and find a core memory managing function called mmap (sort for memory mapping). Its what the OS uses to load DLLs and do many other stuff. Suffice to say I had no clue what I was doing. I just copied an example I found online and I was literally printing (printf()) bytes and disassembling machine code. Last time I worked as low level was 20 years ago. However those prints and endless testing executables show me the details that documentation would not show and I was able after days of really sad efforts to finally accomplish my goal.
Of course as always it made me wonder how simple it was and yet how much time it took me to learn it. Of course now its simple because I know how to make it work. So you can say simplicity is certainly relative.
Thats life, huge, complex and impossible to fathom and never ending learning process.
Your blank mind is fine, keep learning , testing and experimenting and you will be fine. You don’t need special genes, special IQ or special anything to make games in Unreal.
The only thing you need is not giving up and keep trying until you make things work no matter how many times you will fail.
But then this is how life works I am afraid.
If you need inspiration, just take a look at a baby learning how to walk. A seemingly doomed effort , of never ending colliding of the face with the floor. Its painful physically and emotionally to watch.
But baby are morons, actually the word “moron” comes out of the Greek word “moros” which also comes from the word “moro” which means “baby”. So to say that a baby is acting like a moron, literally means to say that a baby acts like a baby.
Baby and kids are morons because they don’t know when to give up. Apparently that makes them great learner. Its like kid that annoy you with a never ending amount of questions today, tomorrow will be showing you how to code in Assembly.
For a kid , there is no challange, difficult , boredom and exhaustion. There is just fun and endless curiosity.
So be a “moron” like I am , and you will see how much easier things will become. Have fun and stop worrying about the result. The rest will come by itself.
Oh sorry I forgot with all this bumbling to answer your question.
When it all clicks ?
Never.
Be glad it never does, thats what makes life fun
