Writing them as they come:

-It's slow, and now that I've been able to play it on an emulator with a fast forward button, I don't think I could ever go back to the cart.

-The fact that they don't talk, allowing you to imagine their personalities yourself as opposed to them all being assigned stereotypical RPG character traits with the hero making you unable to enjoy the game because you're too busy grumbling "the loner, emo hero trend needs to get over itself FAST"-- that wasn't a bad thing, it was a good thing.

-I never was able to do the code to get to the sliding puzzle. I read 48967248905640893564 different sites and examined each way to do it, tried it every way I could imagine, but it never worked. And that ticked me off, even if I'm not missing much.

-The fact that it isn't always obvious what your next stop will be is a bit annoying, but not awfully detrimental to enjoyment.

-Choosing your party and having as few or many mages and meatshields as you want=fun.

-I don't care what anyone says, I like the thief.

-Not terribly challenging unless you do something stupid on purpose (solo challenge, all white mages, etc).

-Level grinding is kind of fun for me. brings back nostalgic memories of my first RPG, Dragon Warrior I. Fighting slime after slime after drake after drake to afford that hand axe. And the music that told you you just advanced to the next level! Good times =)

-I cannot complete the game without screaming at my screen "This plot/ending makes no sense!!!!!" [edited for heavy profanity].

-My 5th favorite Final Fantasy.
