As I wrote in the other thread, new d&d is a different beast from old d&d. As for social interaction, Greyhawk is strongly affected by and builds upon volkenwanderung and how different ethnic groups deal with each other. Including magic genocide MAD, and the setting is also explicitly postapocalyptic. Because the seventies.
I want less new d&d and more old. More Dunsany, less Tolkien. Also I want more gangs and flexible law and the less boring part of feudalism and other interesting societal elements. I want players mingling with those in power for their own reasons.
I go for historical societal structures because they are complicated as hell (without mysoginy because it’s just depressing, but with a lot of disdain for foreigners, because before radio even people from 50 miles over spoke funny and had bizarre customs, and i find it funny even if I’m target of that myself). And when my players slay a dragon (not happened since 2013) it’s more Fafnir than Smaug.
Vanilla is boring.
