I've been a long time fan since I first played it on the GC collection. It has always been underrated, despite its Groundhog Day loop being a unique to the Zelda franchise and an extremely rare but thought provoking game mechanic. I've always thought it was a good compliment to Ocarina of Time, and that game to Majora's Mask. MM was more condensed and detailed compared to OoT's vast, yet vacant, world. Even the water dungeons compliment one another. The Water Temple has puzzles bases on the water's level, while Great Bay Temple was all about the direction of flow.
My only hope is they make it easy for first timers and less tedious for vets. It would be great if playing the Song of Double Time let you select how far ahead you wanted to travel, a la Elder Scrolls, instead of jumping you forward to the next 6am or 6pm. The Owl saves should be permanent, so screwing up after a save with one doesn't necessitate a trip back to the beginning of the 3 days. The well with the multiple fetch quest needs to die in a fire. Stone Tower Temple, while being one of the best areas of the series, had that annoying "go back out side and play with some switches to expose another switch" problem when you had to switch gravity. The Anju/Kaifee quest should be more lenient and give you both rewards at once. And it would be nice if your first upgraded sword traveled back in time with you. I never even use it since the next upgrade is permanent and requires the first upgrade anyway.
It great Nintendo is finally sharing this to a new generation and to those who missed it. Majora is the darkest and most emotional game in the franchise, possibly also in Nintendo's entire history. Link will find and ease around a dozen restless undead souls that can't accept their deaths without his help. He will also take the identities of several to be the heroes for the individuals' loved ones and societies. That has to be some of Ninty's best writing.
