Gen Con 50 featured what looked like some really cool Retrospective Panels about the history of Gen Con and tabletop gaming. Here's the event list. Per this 2017 forum post, they were all recorded, and there were plans to release those recordings.
Does anyone know what happened with that? This would be a great year to unearth those. I wasn't able to make it to any of them (Gen Con 50 had SO MUCH going on), and was looking forward to watching the recordings!
