I'm sure this sentiment has been shared in the thread more than once before, but I'm sharing it again.
Nintendo stories are wacky, silly, and fun, and they're generally just a great pleasure to enjoy and be a part of. There's a sincere joy when traipsing around the Mushroom Kingdom, a dark curiosity when exploring the dark and dank alien ruins in Metroid games, and an amazing sense of adventure when exploring Hyrule. Then they go off and do some out of left field wacky shit like Smash Bros, Mario + Rabids, or Mario Kart and you just have to sit back and laugh your ass off at how crazy it is.
That is easily and every bit as valid as any emotion elicited by a Naughty Dog game or sense of awe inspired by a Kojima production. Nintendo stories focus on the player and player agency, not overt narrative. It's the same reason why S.T.A.L.K.E.R. was such an emotionally affecting game for me- the story of Strelok is irrelevant, but that world and those factions are fucking brilliant.
