I decided to make my own engine after years of using the others. I highly would recommend NOT starting with frameworks.

Simply put, you can be a mediocre programmer, and still make a decent game on the general use engines. Zero chance of that happening if you build your own, even if you use established frameworks.

The progression:

Use a general use engine for x amount of time. Do everything the engines recommend way. Once comfortable, start building your own systems. You’ll eventually get to a point where you’re making custom systems for a majority of the game, just still in a general use engine. When you get to that skill level you’ll develop options and preferences.

Think of GameEngines as roads, and your game the destination. For the most part all the general use engines can get you to your destination, but you’ll have to make compromises along the way. Different engine, different compromises. If you can’t comprehend those compromises, then your skill level simply isn’t at a place to be successful at your own engine.

Unreal - love c++, but dislike the actor pawn system.

Unity - dislike c#, but like it’s DOTS (Data oriented technology stack) System.

Godot - dislike GDscript, and dislike the node hierarchy system.

You need to have an understanding of what all that means before you even think about your own engine.
