The story doesn't drive the game in Skyrim. The open world is what drives the game. You can completely ignore the main story and just faff about in the world for hours with no consequence to delaying the main quest, that's hardly what I would call being driven by the story. Compare that to a Bioware or Witcher game and you can't do a whole lot in those games without advancing the story somewhat.
From what has been said so far about Witcher 3, you can actually ignore the main quest and the quests will expire if you ignore them too long with consequences for that, so if true, you'll actually be driven to complete them and not just faff about the open world.
