@OutofPrintArchive The letters sent over Nintendo Wi-Fi Connection were actually a barrier to entry for the Legendary Blacksmith quest line. The “best” piece of equipment for each job couldn’t be obtained if you didn’t use it and reach job level 99, though the game is certainly able to be completed without.

Final Fantasy IV DS was the better game for what it added over the original, such as thought bubbles when paused, the music box, Whyt minigames, the Augment system and 2 superbosses.
