Anything else but the desert. I know they are both 2 completely different games. But if an Elder Scrolls game took place in one. It would feel like Fallout to me. Also a desert really wouldn't have that much wild life running around and you wouldn't have areas like the ones we see in the current Elder Scrolls games. You would mainly be seeing sand the whole time.
I think it would feel pretty different myself. Alik'r i suppose to be a very sandy desert (isn't it?) with massive shifting dunes. Nothing we've seen in fallout before. Elsweyr would also be one of my top choices, since its a mix of Desert, Badlands, Jungle, rocky desert... the terrain is pretty varied.
On subject with the shouts... I don't believe
we should have access to them in the next game. While I personally love them, they are suppose to be a gift to the dragonborn. Anyone else takes years just to learn a single shout.
If we go to Alik'r, I would love to find some ruins and resurrect the magic of the Sword-singer (and possibly adapt it to more than just swords)
The Sword-singers (or Sword singers) were a group of expert http://www.uesp.net/wiki/Lore:Redguard warriors from http://www.uesp.net/wiki/Lore:Yokuda and, for a while, http://www.uesp.net/wiki/Lore:Hammerfell.
The origins of the singers lie in a group of desert artisans, originally recruited from amongst the offspring of high Yokudan families.http://www.uesp.net/wiki/Lore:Sword-singer#cite_note-RTHTH-0 They built a temple to the gods of war and a training hall named "The Hall of the Virtues of War" in which they could practice their combat skills and the art of forging powerful swords. In http://www.uesp.net/wiki/Lore:First_Era#1E_617, the emperor Randic Torn started a divide between the singers and the common people by restricting the wearing of swords to the singers.
Men joining the group were known as "Brothers of the Blade" and women as "Maidens of the Spirit Sword".http://www.uesp.net/wiki/Lore:Sword-singer#cite_note-NFRH-1http://www.uesp.net/wiki/Lore:Sword-singer#cite_note-FTMS-2 Two sources suggest that new members were recruited into the order at age eleven, but is unclear whether all recruits joined at this age.http://www.uesp.net/wiki/Lore:Sword-singer#cite_note-DtS-3http://www.uesp.net/wiki/Lore:Sword-singer#cite_note-FTMS-2 Certainly, one of the most celebrated singers, http://www.uesp.net/wiki/Lore:Frandar_Hunding, was so skilled in swordsmanship by age 14 that he could use his abilities to provide for his mother and four brothers.
The greatest of the sword-singers were known as Ansei, or "Saints of the Sword" and formed their own training schools to pass on their skills.http://www.uesp.net/wiki/Lore:Sword-singer#cite_note-RTHTH-0 To become an Ansei of the first rank, a sword-singer had to demonstrate an ability to form the Shehai, a sword formed out of the singer's own spirit. Higher ranks were also possible.http://www.uesp.net/wiki/Lore:Sword-singer#cite_note-FTMS-2 The study of the Shehai was known as "Shehai Shen She Ru", the Way of the Spirit Sword. When formed by a high-level Ansei, the Shehai was "an unstoppable weapon of great might" and made the singer capable of astonishing feats of swordsmanship.http://www.uesp.net/wiki/Lore:Sword-singer#cite_note-RTHTH-0http://www.uesp.net/wiki/Lore:Sword-singer#cite_note-FTMS-2
In around http://www.uesp.net/wiki/Lore:First_Era#1E_780, the Yokudan Emperor Hira became afraid of the threat he perceived from the singers and launched a campaign to wipe them out. Frandar Hunding devised a strategy he called the "Hammer and Anvil", and eventually won a decisive victory against the emperor at the foot of Hattu Mountain. The war made the singers aware that they were no longer welcome in the land, and they set sail from the port of Arch, eventually arriving in the land they named Hammerfell.http://www.uesp.net/wiki/Lore:Sword-singer#cite_note-RTHTH-0
By the 2nd century of the http://www.uesp.net/wiki/Lore:Third_Era, the Way of the Sword was still being studied but many of the ancient secrets had been almost lost, with even the most venerable masters only capable of forming insubstantial Shehai.http://www.uesp.net/wiki/Lore:Sword-singer#cite_note-NFRH-1 The ways of the Ansei are still admired by other warriors, and at least http://www.uesp.net/wiki/Oblivion:Amulet_of_the_Ansei has been named in their honor.
From what we've seen, quite a few of the races seem to have some historic form of magic that nobody else practiced.
