Hi @s0lidOz
That was one helluva read. And a tough nut to crack.
But a simple response is probably better than a long one.
Best way to learn is firstly decide what area you want to work in. That will then be your main focus. Logic, animation, modelling etc etc.
Then consider designing a small game, something you can do yourself maybe only a little help.
Plan your game out then start. What this will do is make you focus on 1 aspect of the game and you can then find tutorials on the aspect you are working on.
Ie say its a moving block game, how do you make the floor? How does the block move?
Youtube tutorials that are free are aften as invaluable as paid courses. I have taken some udemy courses. One was terrible (well considering it was an ULTIMATE guide to… it was a beginners so jmm) but i took a niagara vfx one that was VERY good. Udemy do a paid monthly subscription which may benefit you its about as much as 1 course costs when they have their “sales” (every week).
But seriousley there is a wealth of free tutorials and help out there including on here.
This is one of the best help resources ive ever seen. Go to stack exchange u get flamed for asking something regardless. Here you will get really good answers and opinions and no grief.
So in essence pick yourself something to achieve a small term goal and start learning.
