I find Majora's Mask to be one of the saddest and oddest games made by Nintendo, or maybe ever. It was a very good game, very atmospheric, very devastating... It just had an amazing concept.
The idea that a small boy was searching for his fairy friend that left him, but he gets robbed by a Skull Kid whom which he had befriended and taught a song to. He loses his only friend, his horse, he loses his most valued possession that a princess entrusted to him, the Ocarina. Then, his so-called friend transforms Link into an incapable-of-anything wood-man and leaves him in a dark forest. He tries to leave, but instead he was pulled into a world he never knew about, and he is seeing people he thought he had known in Hyrule -- but they're different. He doesn't have a friend in the world, and then all of a sudden a derranged salesman asks him to retrieve a mask of great power in three days, or otherwise the moon will crashland and kill Link and everyone else in Termina... Talk about pressure.
But it's not just Link's story that was touching... Link wasn't trusted to save the land as a whole, but to save everyone individually. Everyone was in peril, and they let you know. Anju tells of her tragic loss of her fiance... During the final hours of the final night, she sits on her bed and hopes for nothing else but to see her love enter the room... She might die, but she believes she will see Kafei again. And then, in an instantaneous second, her emotions come to a hault, and she awakens three days before -- not aware that a small boy will try his hardest to reunite her with Kafei.
I suppose that's why I love Majora's Mask so much. Because it creates characters, emotion, sadness, love, darkness, betrayal, insanity, friendship, trust and, well... so much more. Majora's Mask is a wonderful game.
