In my mind, Greyhawk is the ur-DIY setting, especially for the swords & sorcery (as opposed to High Fantasy) crowd. What made the setting great at the time is that it didn't provide answers- it provided hooks.
perhaps some additional, appropriate archetypes would be nice.
What setting specific archetypes do you think it needs?
Her Greyhawk map is amazing! I stumbled across the earlier version a few years ago, amd was stunned by the quality. I'd love if she, or, more likely, someone else with such dedication, would do similar maps for other settings!I'd love 5E Greyhawk setting just seeing Anna B Meyer's Map of the Flanaess 2019 Edition the other day got me all excited!
