Legend
Stone Age or PL0 is very much a hard one to conceive of and have as an interesting setting location, I think most of D&D sort of looks over something like that. Though such a place could have the "primal" spirits that quite readily interact and be present in the material world. And course there's always the idea of throwing in dinosaurs in such a place, it goes with the theme.
Bronze/Iron Age or PL1 is covered by Dark Sun and maybe some of the 2e historical guides like Glory of Rome campaign book which I've never read. Dark Sun I feel is perhaps the most prevalent setting for that progress level.
