I am using the
World of Jordoba setting for my DF campaign. It's systemless, but clearly written with D&D assumptions. That makes it fairly straightforward to adapt for Dungeon Fantasy purposes. I like that the world is broadly described, and with evocative details, but plenty of space for the GM to make it their own. The setting has a sort of "Gonzo Sword and Sorcery" asthetic to my mind, although it's easy enough to change that.
B2 Keep on the Borderlands has been dropped onto the map, and the party is currently running through that.
