Ask HN: What's Your Favorite Game Dev Video Lecture?

I'm absolutely loving the video presentations from GDC: https://www.youtube.com/@Gdconf And wanted to find more non-GDC video lectures about making of video games, game design, board games, game mechanics, or generally gamificaiton.

My favorites so far have been: "How I got my Mom to play through Plants vs Zombies" , "Designing Marvel Snap", and "Balancing Mechanics for Your Card Game's Unique Power Curve"

What's your favorite?
