It's pathetic but great at the same time...
Pathetic because it's just another episode of Nintendo being a typical possessive jealous bf/gf.
But great, because putting Samus in such a mind-numbingly mediocre and lowest common denomiator game just feels cheap.
Fortnite is not Smash, your characters won't be treated like a Queen or King here, they will be treated like a 1 dollar bitch.
And even though that wasn't Nintendo's reason for declining, I indirectly appreciate that they did decline.
