The comparison has been around for a long time; I first encountered it in an early edition of RuneQuest. It may even have entered that status of "everyone knows that," but I haven't run into much reflection on its content.
Grégory Meurant opened a conversation with me about it. He's posted here before about playing Sorcerer, and having read Howard Becker's Outsiders and related work, decided it was time to investigate. Here you go!
I think it's one of the strongest conversations on the topic in my experience. I'd really like to know what you think.
