Definetly the best of the Famicon era FF's and the game still easily holds up to today's standards. I have actually never heard any real complaints with this game and though I wish I had played the original the DS version has made me quite happy since it's far from a lazy port.
The gameplay is fun (am I the only one here who feels the Geomancers are just insanely broken?), the story is especially incredible and deep when you realize when it was originally written. Desch, Unne, and Doga are some amazing characters and it definely has that old school addictive charm.
I'm still waiting to hear my favorite track from the game though... "Roaming Sheep".
(SPOILER)I have to defeat Doga and Unei so I can go to Eureka.
