Edit: Why am I always the first post of a new page?
If you want rationale as to why I prefer the Famicom version over the remake(s?), it's simple:
In the original <i>Final Fantasy</i> as well as <i>III</i>, I tended to make up my own story, kind of like one would do in a tabletop RPG. My group had their own unique dynamics, aspirations, dreams, and so-forth.
Square-Enix, in their infinite wisdom, decided to take that away in the remake of <i>III</i>. And yet, they kept that aspect in <b>every single remake</b> of <i>I</i>. If any game in the series could have used more oomph in the story department, it was the first one. Not the third one.
And that's why I prefer the Famicom version over the DS/iOS/PSP version. Because they messed with a classic. I would have no gripe if the quartet of Onion Kids had had personalities, hopes, aspirations, etc. of their own, but they barely say two words in the original version, so.
