Lore has been changed before. Where did Imperials come from? Why did Orcs become friendly instead of generic enemies? Few orcs in Daggerfall are friendly. I can only think of one friendly orc in Daggerfall. Since when did Orsinium become populated with actual orcs? When I went to Orsinium while playing Daggerfall,
Except it is clearly explained with several books in Morrowind, which describe the ending of Daggerfall (the warp in the west) that shaped the geo-political landscape of High Rock and Hammerfall
Where did all the cities of Morrowind come from? They weren't all in Arena. Where did the names Dunmer, Altmer, and Bosmer, and Orsimer come from? They didn't exist until Morrowind. When did Orcs become Elves? Why are Daedra now more than just demons?
Adding lore is welcome. I don't recall anyone complaining about what Morrowind added, except for 1 poster complaining about the Imperials springing from no where.
Why couldn't Talos just change Cyrodiil into what it is? That is canon, but people don't accept it, overlooking previous lore changes that first appeared in the main series in Morrowind. Anyway, since when do fans decide what is canon or not? If Bethesda says it is canon, then it is canon. Since Oblivion is the latest game in the series, it's lore is the most accurate of all the games in the series, even if it overwrites some previous lore. Oblivion's lore is official, more offical than Arena, Daggerfall, and Morrowind's lore.
That doesn't make it right to just run up and gut everything the previous games worked on, and what people enjoyed. Also, Talos pulling the god card from his ass was only canon because of a single paragraph long book that MK wrote up as a pity write-off to the fans, because he disagreed with what they did to Cyrodiil just as much as many of the fans did.
4. Fast-travel in Oblivion is optional. One does not need to fast-travel in Oblivion. Play Arena or Daggerfall and you will see what it is like to have to fast-travel. Any fan of the series who claims to want to explore should explore on their own, not be forced to. If you really want to explore, THEN DO IT!
Fast travel, in regards to traveling quickly, is not optional because its a "my way or the highway" system. Either we use fast travel, or we take twenty minutes to run across the landscape. In Morrowind there were up to a dozen ways to travel, each with their own advantages and disadvantages. Boats only ran along the coast. Silt Striders usually only along the land (and could not go over Red Mountain, so it took many trips). Mage's Travel was fastest, but only took you to a number of limited locations. Mark and Recall was fastest, but only took you to a single spot every time (unless you changed it). Almsivi and Divine Intervention only took you to the associated faction areas, which were no very numerous. The index system was diverse and large, but had many indexes one had to collect to be able to use it all. Even then, one can use a jump spell to leap across one third of the landscape at once. Boots of Blinding Speed worked nicely, too.
