Let's face it, Nintendo's got some scary things in their collective head, particularly in the N64 Zelda department. Majora's Mask ranks pretty high just for the moon and the Happy Mask Salesman alone. So what if they decided to take the Nightmare Fuel-per-minute of gaming records they set in their other games and top it?
Well, let's see... What could they do to traumatize us?
A) Totally, completely deconstruct the Pokemon series, particularly the Pokedex entries. Some of this was addressed in Explorers of Time/Darkness/Sky and Orre, but so long as children can sleep at night, it's not terrifying enough.
B) A look at the Sheikah during the Oo T
/MM period. Maybe it's just me, but there's something off about how the traditionally Sheikah Kakariko Village seems to lack ANY Sheikah whatsoever, when it was opened to the public rather recently, with a well to Hell itself and that marker in their honor in the cemetery...
C) More Pikmin. Am I the only one who can't play this game because they're scared of BULBORBS? *Shudder*
D) Majora and the Happy Mask Salesman return.
And then, no one ever sleeps again.
... Which is when I was banned from Arkham Asylum. Any questions?
