Nostalgia is not it's Nintendo Magic entirely though. Those games I stated in the OP really had to create it's magic, being they were the first of it's kind to step each Mario and Zelda into the 3D realm.
For instance, Fire Emblem really has no nostalgic history (since almost every FE tell a new tale of the Fire Emblem), but Nintendo Magic is CERTAINLY present in those games.
Examples are pretty much the whole story of Fire Emblem : The Blazing Sword. Lyn's prologue, The Black Fang, The Four Fangs, and Nergal manipulating everyone, even the Eliwood and Hector to do his bidding. The music is definitely epic as well.
The racist issues that are both in Fire Emblem: Path of Radiance and Radiant Dawn. In those games exists a race that is half man/half beast called the Laguz, but full humans call them "sub-humans" (sub meaning Lower or on the bottom) because they feel they are superior to them. This addresses many of the race issues in todays world too.
And the hidden meaning in Earthbound as well. Pretty much Nintendo's ability to disguise world issues in games we can all enjoy so just maybe, few people can actually learn life lessons while having fun...
