So far I've listened to 1.5 of the videos. I ... don't like Edwards. He comes across as pretentious.
"These are bad games."
"People don't play games correctly."
"You don't understand why you like playing TTRPGs."
Other than being a guy who wrote a game 20 years ago that I've never heard of, I don't see why his opinion should matter.
He's written several well acclaimed games 20 years ago. Socerer, Trollbabe, Cartoon Action Hour.... and more since.
Socerer is one of the most laser-focused designs I've read. His goal is clear, in one's face from the moment one starts reading it, and the game is built to follow-through on it. It offended half my regular group when I found it. The rest when I ran it.
I really recommend Sorcerer, at least as a read. See if you can check it out via inter-library loan.. because I don't advocate piracy, but don't want to put money in his pockets...
...as my experiences with Ron himself are pure toxicity. The man was then a total «bleep»-«bleep». I hold out no hope that he's changed.
He is one of the first English-speaking/writing academics to apply the academic approach to RPGing. (Brasil and Argentina have been doing so longer, in Portuguese and Español, respectively.) He's historically important for the encouragement of the storygames movement, the independent publishing movement, and wide adoption of PDF as a publishing medium.
His historical impact is up there with likes of Marc Miller, Frank Chadwick, Steve Jackson, Steve Jackson, Ian Livingston, Loren K Wiseman, Jordan Weisman, L. Ross Babcock III, Greg Stafford, Steve Perrin, Ken St. Andre, and Rick Loomis....
