I beat Majora's Mask a long time ago on the N64, I remember. I bought MM3D back in 2016ish and I never got around to really playing it. I got to the Great Bay temple and got super busy. Well the last few days I went and collected all of the masks.
I went to the moon, and started to donate all my masks to the children. The goron part and zora part, OMG I forgot how hard they were LOL. I got all 4 heart pieces and got the Fierce Deity Mask, and finally beat the MM3D game.
Those moon quests are kind of bullshit though lol.
