Given Todd's Howard's claims about supporting TES VI with DLC for years, I think the scope of the game warrants discussion.

When I first started speculating about the TES VI sometime around 2014, the consensus on the old Bethesda forums was that a multi-province game was not ideal, as that would mean less time and resources was dedicated to fleshing out the unique cultures of each province. A lot has changed since then, Bethesda Games Studios has grown significantly, and its more recent releases give other causes for concern, but nevertheless the point still stands.

However, with Todd Howard's comments about wanting to support TES VI with yearly DLCs, something akin to a multi-province game could actually work. While some concepts are sadly left on the cutting room floor during development, their post-release content is in some cases far bolder and more interesting.

For example, a Hammerfell game could have several DLCs set in the regions of neighbouring High Rock, perhaps even with an over-arching plot revolving around the dissolution of Imperial authority and the resurgence of the Lariat Dynasty. If some sort of sailing mechanic was introduced, DLCs could be set beyond their borders, taking us to the forlorn colony of Roscrea, the sunken ruins of Yokuda and even Auridon in the Summerset Isles.
