I'm following what you're getting at, it just feels the dev quoted makes "fiddling around" sound like an undertaking - users need to build custom lighting or change the engine in some way to get similar results. The real extent of fiddling in this case is dropping a node into a scene and making a few pointed selections.

Users preform this action a lot in godot. Everything rendered starts as a node, dropped into a scene, and making selections. Making a game would be "fiddling around" under this same context.
