If they remake this game I want them to do it right. And that means no half-assing it like the cell phone version that came out earlier this year, and it also means nothing like the DS/PSP versions. I want a full HD 3D remake with current-gen graphics, a full orchestral score, and at least competent voice acting. I'd also like to see an update of the battle system like what they did with FFIV's DS remake; incorporating some features of the job system would be nice, for example.
There's more but that would be a nice start.
