Not the myths you're thinking of.
The Flintlocks and Witchery blog had this post up and I just read it. I have to say I agree completely with the sentiment here. As I was telling the author, the concept of the highly-lethal D&D experience that has been so widely disseminated through the OSR scene was absolutely not how we (me and my gaming cohorts) played the game back in the day. I can't remember a single character death that was the result of the kinds of things you see in, for example, DCC RPG. We were nerdy drama queens. We did stories. We had epics. We had characters.
Not that I'm opposed to the DCC RPG style of brutality. I love that shit. But that's not how we played D&D in 1984, 1985, or any year through 1990 when I more-or-less abandoned the game.
The insta-kill traps and PCs with 1 hit point were not part of my entry experience to this wonderful hobby. Those ideas didn't filter into my experience at all until the OSR.
