Majora’s Mask is a hidden gem if you ask me, it doesn’t get nearly the same praise as OOT because the latter was more friendly with the public, and this one is… Well weird, but the perfect one for Halloween season no doubt.
I have only played the 3DS version and I enjoyed it, as others have pointed out, you really need to do the side quest as they are a huge bunch of the game, I completed it 100% I think, but I always had a guide on my hand because I’m dumb.
As for the replayability time… Yeah I don’t see myself coming back to his one in the near future (maybe on Halloween though), other Zelda titles like OOT and Twilight Princess? Sure!
