Godot is a fantastic game engine, you'll only need to make a few small games to actually know what you're doing with it ! We uploaded our first 3d game made with godot today and I think it's pretty good, considering I was the sole programmer and didn't know a thing about the engine 6 months ago !
You can try it out here if you want ! :p https://itch.io/jam/extra-credits-game-jam-6/rate/736364
Good luck with your Godot journey, the engine is growing rapidly and so is its wonderful community !
GDquest makes wonderful tutorials if you are starting out and need... well basically anything :)
