All the extra/hidden stuff, like many of the summon materias, the whole chocobo breeding and racing sidequest, the golden saucer, etc.

And did I mention the music? I've actually gotten quite bored with the story over the years, especially after all the irrelevent extra crap they've produced lately, but the story written into the music is still as fantastic as it was when the game first came out. I think if the idjuts at SE would remake the original game (as everyone wants, not all this superfluous crap) with updated graphics and a revamped translation, many more people would come to appreciate the game. I can understand why gamers who joined the FF community after FFVII would have trouble going back to FFVII after playing the newer games. The graphics (especially character models) are absolute crap, so much so that it's hard to find any enjoyment in it. The movies are still good though, I remember seeing the commercial trailer for the first time and flipping when I saw Leviathan in CG splendor. I think any FF fan should at least play through it once. Likely they'll find something to like in it by the end, and it's certainly worth experiencing once if for no other reason than to understand the roots of 3D FF. It's like a fun playable history lesson.
