Tes VII (7) should be called "empire" and have the entire continent (you'd need it with the falmor) The player is created by some daedra and gets to Lead every nation if they so choose into war. They can rebuild the declining empire or dominion, take back morrowind from the argonains, start wars amoungst provinces (or factions- necromancer armies included) and the aim of the game is to either create anarchy or an empire (which may please the daedra) Perhaps akavir could invade halfway through the game to really [censored] things up?
That will deal with all the amazingness.. expansion pack time? uhhhh.... i dont know!! Perhaps hammerfell or high rock? (high rock is rather small compared to skyrim) Maybe a city that is in fact an actual city?
Ambitious are we? That would be the last TES as we know them, the end of the prohecy about the Elder Scrolls. The end of TE Sgames in Tamriel at least.
I doubt we see anything even close to that before 2030-2035 as they still got several provinces to place a game in, and we must think fo the tech.
If they do Alinor and Valenwood with TES VI, they'd have Elseweyr or/and Black Marsh for TES VII.
Then they'd probably remake High Rock and Hammerfell in TES VIII and finally TES IX: Tamriel in the end.
Well, Akavir next.
