From the preview:
"If you choose to view Final Fantasy IV for the Nintendo DS as just another port, then you'd be gravely mistaken. Rather than just altering a few things, adding some goodies and slapping the game on a new system, Square Enix has taken its time and remade one of the best games in the series. If a list would be made tomorrow of the best DS games released in Japan, FFIV would be in the top five. This is the best RPG available for the system, and I can't wait for the announcement that it will be released in English."
