You should do WW. It is a very easy zelda game. Majora's Mask took some time and it has some pretty high difficulty. You should go with it 2nd, OoT 3rd, LoZ 4th, ALttP 5th, Tp 6th, and AoL 7th. These are the ones I've played.
i think you are awesome you beat wind waker you beat majora's mask you know i suck at zelda i only beat 2 bosses on wind waker and beat 1 boss on ocarina of time -.-
