I’m about the most passionate advocate for Gygax and 1E that I know, but I don’t (at least not recently) say that people who don’t play that way are doing it wrong or should play differently, and hope I don’t come off that way. My motivation is that I really like that style of play and feel like it got totally neglected, virtually erased from history, in the 90s, and then when it supposedly came back in the 00s it was as a cartoonish distortion (ultra-high lethality, arbitrary, etc), and even now it’s been heavily overshadowed among OSR types in favor of ultra-minimalism, so it feels like it’s still worth making the case in favor of Gygaxian 1E. Not for purposes of evangelizing or trying to get anyone to play differently (assuming they’re having fun) but more both so people will understand what I’m actually talking about when I talk about the way I like to play and also (though this is probably futile and Quixotic) so maybe fewer people will use “Gygaxian” as a shorthand for either arbitrary “killer DM” style play or reductive ultra-minimalism, which is never what it was about.There are a few folks out there who claim that Gygaxian AD&D is the Perfect Game and that most of gaming and fantasy has been doing it wrong for the past thirty years or so. They don't seem to hang out here or at theRPGSite, though, and they've all been banished from TPB; I tend to run into them on Twitter due to some mutual connections.
The biggest thing I get from them is that whatever I want out of gaming, Gygaxian AD&D 1E isn't it.
