It has been said that a Majora's Mask remake is not impossible and if enough fans show commitment, it could be made. However, what kind of changes would you like to see? New dungeons? Better mask usage?
I honestly have no clue, because I have never played the original. I would like to see more dungeons and possibly more side-quests, but that may be a bit too much considering you have to deal with the 3-day time limit (72 hours), even though you can go back in time.
