The process of implementing the internal structure of a game engine myself and even building a game on top of it was very impressive. It allowed me to understand how the engine operates structurally rather than just using its features, which was a huge help in grasping the flow of how a game is built on top of it. I believe this is an excellent course for building a solid foundation as it allows you to directly experience the relationship between the engine and the game. Additionally, the instructor's explanations were clear and well-delivered, which helped a lot with my understanding.
