Sadly there is not open-world equivalent of education-by-gaming. I feel every learning path is preset with fixed dialogues. I can not explore the topic I like, it's too easy to hit the boundaries of human knowledge. I feel game design technics can be applied to know-how and know-what learning, but for know-why learning, we need more advanced AI.
