I feel like literally everyone missed the point of this thread, that being what aspects of your favourite game's narrative is most interesting. Spirit did present the thread specifically in relation to story, and even gave examples of the kind of thing she expected in response.
On that topic, my favourite game is Majora's Mask and the most interesting thing about it, narratively, to me, is the tone. How can a game that is entirely about healing a broken world and making things better feels so bleak and hopeless almost all the time?
Termina is in turmoil and Link is doing everything possible to help it. Over and over, fixing peoples' problems, making things right, removing curses. That should feel good, it should feel rewarding. But it doesn't. MM feels like fighting against a heavy current. There's so much going wrong in Termina and you only have three days to fix it all. It's literally impossible. You cannot help everyone. You cannot fix everything. And the things you do fix break again once you turn back time. Two steps forward, three steps back. Even releasing the giants feels hollow. The melancholy Oath to Order, the giants standing so far away, obscured by clouds — they feel as distant and remote as they did before you defeated the boss and freed them.
The game is full to the brim with little moments of hope — Anju and Kafei's reunion, the Deku Princess releasing the monkey, Lulu's eggs hatching, Igos du Ikana's spirit accepting death, Pamela comforting her father — but each and every one of them is reversed when you play the Song of Time. You keep saving these people only to see them in trouble again. As the game goes on, you become more and more aware of how futile your actions are. I remember feeling a sense of pointlessnes the first time I went to the Great Bay because I knew that after all the effort of saving Lulu's eggs they'd only get stolen again, and next time I wouldn't be there to get them back.
That tone so integral to my love of the game. MM isn't about saving the world in the same way Ocarina or Twilight are. MM is about the perseverence and dedication it takes to do great things, and the pure belief that if you just keep fighting on you can succeed. MM doesn't expect you to save the world just because. It beats you down with an overwhelming tone of hopelessness, inviting you to give up, and that forces you to find your own reasons for saving the world, for continuing to fight against the inevitable.
Figuring out why MM made me feel the way it did, despite what I was actually doing, drew me into it so much and made for an engrossing experience unlike anything else I've played. The tone, contrasting so much with the plot, elevated the game to a whole other level for me, and it's been so close to my heart ever since.
