I 100% Majora's mask , I recommend you do it as well. Trust me it's better than OOT and WW combined.

The reason why I like MM vs other LoZ games is because of it's darkness. Pretty much Link is on a journey to save everyone in 3 days and if he doesn't do this, he and everyone dies. There is so many moment's in this game that want to make you cry , the soundtrack fits perfectly with the game and really adds a layer of darkness to it. And even if the characters are recycled from OOT they still have there own distinct character.
Another reason to like this game more VS other LoZ game is that it isn't like any other title in the series, your not trying to save a princess or anything , your pretty much trying to save yourself.
