Legend of Zelda, The - Majora's Mask (USA) ROM

This is an absolute BEAST of a game. Out of any n64 game ever released, this probably has the most content, thanks to the expansion pack.
The story begins as you ride on epona through an unnamed forest as a kid. 2 fairies, similar to Navi, come and start bothering you. They knock you off your horse and you pass out. A skull kid wearing a mysterious mask, later revealed to be Majora's mask, steals the Ocarina of Time and turns you into a Deku Scrub!
You have 3 days to complete a series of quests to turn yourself into normal Link. 
It is revealed to you that Majora's mask has mysterious, dark power, and the world will end with the moon crashing down onto it if you don't do something, quick! Fortunately, your trusty ocarina has the power to turn back time and give yourself another 3 days.
Anyway, if you remember Ocarina of Time, there are only a handful of sidequests, and the main focus was put into the main quest. Not anymore. While there are only 4 dungeons compared to Ocarina's 9, there are infinitely more side quests, mainly based around masks. To put it into perspective, there are more masks then there are regular items, and each one has a different effect. The bunny ears increase your run speed dramatically, the bomb mask creates an explosion, and the stone mask basically makes you invisible to most enemies! Each mask has it's own side quest, which can take anywhere between 5 minutes to a couple hours to complete. 
Once you've gathered all the masks, you get the fierce deity mask, transforming you into a demigod with massive power and the ability to shoot lasers from your sword, similar to older Zelda titles.
This game is definitely darker than any other Zelda title. As you play through the game, you can't help but feel a sense of foreboding, as if something terrible will happen. This is compounded by music that gets darker and darker each passing day. By the third and final day, the music is so dark, a feeling of dread washes over you. This is a very emotional game, and as you meet characters, make friends, and complete side quests, you actually feel like you HAVE to stop the end of the world.
I recommend this game to anyone.

The Legend of Zelda Majora's Mask is a great game for the more experienced Zelda players. The game has many interesting and hard maps that will you on the edge of your seat all the way!

While everyone knows about the greatness of Ocarina of Time, fewer people know just how amazing Majora's Mask is. In your quest to save Termina from destruction, you travel through a variety of terrains using Masks and items to pass through obstacles. The most interesting feature is that you time travel back to Day 1 of 3 to save the game, which you'll be doing a lot. With a great soundtrack, graphics that take advantage of the N64's Expansion Pak, and a story that keeps you going, Majora's Mask is a definite classic.

Ocarina of time sequel, but tottaly diferent. You will have three days to save Hyrule! Fortunantelly link can go back to the first day, but some actions youīve done will disapear.
In this game Link will use masks to obtain powers, or just to use because you like it.
Itīs a great game, even if you havenīt like ocarina of time, if you do, probably will like this one to.

This game plays very similarly to Ocarina of Time, yet it adds a darker overture and a sense of urgency to the game.
While in Ocarina of time you could spend however much time you wanted in any of the dungeons, in Majora's Mask you are limited to 3 days in game time, or about 54 minutes, including travel.  Though this can be sped up by the use of owl statues, similar to the songs related to specific temples in OoT.
The game also originally made use of the N64 "expansion pak" allowing for increased draw distance and real time rendering of building interiors.
 
Overall, the game was similar enough to OoT to be able to pick it up, but different enough to keep you interested in the story the whole way through.
