I'm not really a big gamer, but lately, I've fallen down this rabbit hole into the world of Casey Muratori, and this project that he started on Twitch in 2014. He is building a video game from scratch and explaining it all as he goes along. Casey is a professional video game and game engine, creator. He has been doing it for over 30 years. His approach to development feels a little bit like it's from the 1970s. Yet, it resonates with many smart people who are learning how to truly build things and understand fundamentals from Casey.
Casey has a lesson about learning and teaching for us all.
