My ultimate TES game would look something like this:
Foremost it would be called TES VI: Alinor and it would be set in the Summerset Isles/Alinor for two reasons. First would be the foreign and interesting landscapes and architecture alluded to by Jacki above. Second would be for the purposes of the story. At this time the Thalmor rule Alinor. No matter what race you choose you start the game out as just another slave brought into Alinor to do the manual labor (I do not see the Thalmor doing such menial tasks themselves). This allows us to uphold the Bethesda tradition of beginning every TES game as a prisoner of some sort.
However, your status as a slave is only a cover. You are, in actuality, a Blade sent by the Elder Council to help destabilize the Aldmeri Dominion through any means necessary. To do this you end up in alliance with a resurgent splinter group of Altmer calling themselves
The Beautiful. From there the main quest would involve political intrigue, espionage, and assassination all for the purpose of bringing the Dominion to its knees. At some point you become the most hunted man/woman in Alinor with guards and other officials ordered to kill you on sight. There would also be a love interest involved for those into that kind of thing.
Factions involved:
- The Mages Guild, of course. They are in an eons long battle against their rivals in the Psijic order. Only one of the two would be joinable in any one playthrough... and there would be a prerequisite of magical skill necessary for membership. Sorry warriors and thieves, mages only need apply.
- The Fighter’s Guild would be there for mercenaries looking to make some extra coin. Skill with weapons is encouraged though not necessarily required. For those belonging to one of the Dominion’s pilot races (Altmer, Bosmer, or Khajiit) there would be a small assortment of knightly orders joinable, each with their own story and conflict. For membership in one of these weapon skill is a prerequisite.
- The Alinor Thieves Guild would be in the most direct conflict with the Thalmor Hierarchy. One could choose to ply one’s nefarious trade (prerequisite skill required) or, if Altmer, one could choose to join the enemy (if only to destroy them from within).
- The Alinor Dark Brotherhood is at war with itself. Following Greywyn’s teachings a splinter group of vampires within the order have founded a new chapter of the Crimson Scars. Only one faction can claim Alinor as territory. Will you be the one to tilt the balance of power? Note: one must first have the necessary skills to be approached by the DB, then one must be a member of the DB before contracting porphyric hemophilia in order to join the Scars.
Add to this the usual side quests and random dungeons in the wild and I'm good to go.
