Which Japanese RPG Had A Really Good Story?

[Paatar]

The Xeno series (Saga, Blade, Gears)
The Fire Emblem series. Practically all of them. So far, mainly Radiant Dawn and Awakening IMO.
The Shin Megami Tensei series and it's spinoffs (Persona, Devil Survivor, Devil Summoner, etc)

Also all the Golden Sun games. :D
