Arena is all of Tamriel. Daggerfall is in the Illiac Bay, which consists of part of High Rock and Hammerfell. Morrowind is on the island of Vvardenfell, a region of Morrowind.
The reason that people would like to see one province is because the game can be made with greater depth and detail. Arena and Daggerfall were huge, but boring since it was all computer generated and bland. Sometimes bigger isn't better.
And in my personal opinion, since the world is much larger than portrayed in game, more than a single province would make the world seem small.
Yeah, I knew all of that. I probably didn't make it that clear, but what I meant was it doesn't have to be the whole province. It could be a specific region in between provinces Daggerfall style or whatever (though obviously not on such an absurdly giant scale), or a region(s) inside of the province. The problem with Oblivion was that they took the biggest province and made it to the same scale in which Vvardenfell was created. Which is what I mean about the scale being bad.
Southern Morrowind (not Vvardenfell) and north-western Black Marsh.
The geographical, cultural and political situation there is very interesting, especially after The Infernal City. I'd imagine the Empire, since peaceful ways are unlikely to work, would start an invasion against Black Marsh sooner or later, struggling to secure more than the West, but not really needing much more than a larger outpost to see what's going on in the Province, since Argonia is not very interesting for the Empire and they'd only need a town or two there to claim the country theirs.
The player would probably start out there, there'd be an unconventional warfare-like atmosphere at the "border" to the "wild" Marsh, and deeper within the country the player would meet exotic creatures, culture, vegetation etc. That place would be very dangerous, but the hero would try to bring peace to the region. The main quest might then lead the player up north, at first to the very southern Morrowind, partly controlled by what remains of the Argonian population there after the Umbriel incident. Going north, things become even worse, and Dunmer daedra-cultists would be everywhere - however, those would not be "bad guys", but the player would instead learn about the culture of those Dunmer who came back to Morrowind, and the main quest could resolve around bringing peace to the region around Cyrodiil, Marsh and Morrowind and uniting these areas under the Empire.
Especially Morrowind would be interesting, since alot has changed, and the Dunmer who might eventually re-populate it would be alot more mysterious and alien than they already were, since they live in a damn unfriendly environment and want to stay away from the Empire and the Argonians. The Argonians would be split in two parties, the An-Xileel and the now very rare empire-friendly Argonians... (Depending on what happens in the second book, the situation will probably look much different, but interesting nonetheless)
I just think the area there has alot of potential for a fantastic setting, not unlike Morrowind, and for politics and stuff.
This is exactly the sort of thing I'm talking about, and I too think that that area would be a good choice.
I just think the whole one province, the border of where you can go is dictated by the province is sort of boring :shrug:
