The Myopic Sniper said:Not that D&D is in anyway reflective of history, but it sounds like they have simply shifted the default political, technological, economic and social assumptions from a pseudo Western Europe of the Late Middle Ages (1300-1500 AD) to the Early Middle Ages (500-1000 AD). I don't think they will kill any tropes such as Full Plate armor. But I think the idea of being able to walk into a small village and ordering it from the Armorer off the shelf is probably going to be reflected in its cost and its availability on treasure tables. No black powder weapons even being an option would be a good guess.
However, each PHB/DMG cycle could allow for different defaults. PHB 2/DMG 2 could assume Late Middle Ages or even Renaissance setting. Hello gunpowder rules, rapiers, Gnome tinkers, great sailing vessels, guidelines for creating Empires, tables of royal titles, rules for building organized armies and constructing huge castles. Release a setting book shortly afterwards that supports such a background and you start giving DMs and players a couple of different sets of coherent visions for play.
Different areas of a campaign setting could have many different cultural assumptions. For example, in one area, a kingdom or empire may have collapsed, while civilization is thriving elsewhere. (For examples, contrast Western Europe, circa 500-1000 with the Byzantine Empire and other surrounding regions.)
In the Forgotten Realms, there are large areas of the North that have little formal government, and that is true for some other areas as well. Perhaps the implicit campaign setting implies that the setting is in need of heroes. However, it is hard to find a fictional world that is not in need of heroes. (Even in a strong civilized state, there are always dangers from within as well as from without.)
