I would call Godot/Unity/GameMaker an engine-IDE. You can have an engine like Love or pygame where the engine is literally just a shared object or dll and you need to basically supply your own tools for level design, programming, etc. Engine-IDEs are one-stop-shops with nearly everything you could need built in (level editor, code editor, particle effect sandbox, etc.).
