Skyrim is a "sequel" to oblivion but doesn't have much to do with oblivion other than the setting. Different story, different game mechanics. But its still a great game.
it also isn't called Oblivion 2, or Morrowind 3, or Daggerfall 4. It's "The Elder Scrolls 5: Skyrim"
All of those are called "The Elder Scrolls" + word(s). Dragon Age: Origins same case, DA + numbers/words. Mass Effect and Witcher are closer to naming used by Baldur's Gate. They all have something in common, but also enough difference.The Star Wars RPG series, Final Fantasy and even Divinity Original Sin 1 vs. 2 are very different. All these are more different than alike, except the Assassin Creed series or something like FIFA.
