Why is FF III so good?

[Kawaii Ryûkishi]

It's to the FC/NES games what FFVI is to the SFC/SNES games. Its story is more intricate than those of its predecessors, with numerous NPCS with their own backstories and sub-plots, and for the first time, the main villain actually had motivation for being evil and all. FFI and FFII were very similar in terms of graphics, but FFIII's graphics are miles beyond theirs and very impressive for a FC game made in 1990. It also was the start of many things that became recurring in the series--healing springs, the Onion Swordsman, Summoners, Geomancers, Bards, Magical Swordsmen, the Knight sprite, Thieves that can actually steal and pick locks, Dragon Knights that can actually jump, Ninja that can actually throw, the concept of "Scan," the Fat Chocobo, Frog status, multiple airships, submersibles, optional dungeons and side-quests, hidden towns, changing jobs mid-game, playing piano, wacky comedy, etc.
