Welp, emotional doesn't mean just sad really but it's difficult to not rank the saddest moments or disturbing ones in Nintendo games because they do stuck out incredibly in contrast to their usual affairs.
Here's my non-exhaustive list :
- Mother 3 ending sequence has a whole.
- Famicom Detective Club Emio last chapter and the epilogue has easily the most disturbing and mature content of any game they published before.
- Xenoblade Chronicles series is basically chock full of incredibly diversed emotional moments notably, the ending of Torna, XC3 Chapter 5 and many others, any time Tomorrow with You plays in XC2.
- Super Mario games ending sequence are usually some of the happiest moments you can be while playing these games (Except Galaxy 1 lol)
- Kirby games have the hypest final boss attack moments you could want.
