Isn't that a huge effort? I remember few games which developed their own game engines from scratch (factorio, limbo, bg3). But, wouldn't it be easier and better to use game engines like godot?

I suppose it depends where you draw the line between engine and framework. Factorio used parts of Allegro until 2018.

Engine these days implies one of those IDEs with everything included (scene editor etc). I don't know how or why, but language drifted in the last 20 years or so.
