Neither Cyrodiil nor Vvardenfell were "generated" maps. Those were the province names in Oblivion and Morrowind, respectively, not Daggerfall.
The point which Milkiway was attempting to make was that the size of the game world is dependent on the amount of resources the developers are willing to throw at it, not on the isze of the province in the game lore. The island of Vvardenfell in Morrowind province was relatively small compared to the size of the entire province, yet the actual playing area was almost as much as that of the huge province of Cyrodiil, which Bethesda scaled down to no more than a tiny "county". The island of Vvardenfell in Morrowind was reduced to about 10% of its length for gameplay purposes, but the province of Cyrodiil was butchered down to somewhere around 1% of its supposed length. So what if Valenwood and/or Elsweyr are small provinces; the actual gameplay area could still be larger than that in Oblivion, if the developers choose to do so.
oops my bad i confused Vvarderfell whit Daggerfall,i know Cyrodiil and Vvardenfell were not generated (thank god)
yeah i hear that Bethesda scaled down the in game map of Cyrodiil because it would be too much for new people introduced in the series(i was one of them nut i don't think a big map would be to much to me as a beginner)
hopefully they don't shy at making the next region big since they pretty mch succeeded getting people in to the series whit Oblivion.
