Most of the bare bones of Final Fantasy IV remain intact in this Nintendo DS remake. The game is a standard JRPG which was best known for introducing the Active Time Battle system and for helping to popularize dramatic storylines with fleshed-out characters instead of the previously used customizable but relatively faceless do-gooders. New facets of the remake include 3D graphics, remastered music, a script retranslated for accuracy, the Augment system, mini-game training for a new Eidolon, alterations to the Namingway and Fat Chocobo characters, New Game+ with a pair of extra bosses and the option to use the Stylus.
The Augment System is the most significant change to the gameplay. Characters that leave the party will now leave behind Augments, which can be equipped to other characters in order to retain the special abilities of the departed. Some Augments also offer powers that are familiar to Final Fantasy fans but never made an appearance in the original version of the game. This adds a degree of customization to the heretofore static characters.
The game also introduces Whyt, a new Eidolon or summon monster that has a customizable face, drawn with the Stylus, and statistics that can be boosted by playing mini-games.
With the additions of voice acting and no limitation on the number of items that can be held, Namingway and Fat Chocobo have each been modified. Namingway is now involved in a side quest and frequently changes his own name and occupation, leaving behind something useful for you in the process such as the ability to map dungeons with the touch screen. Fat Chocobo now accesses various options, such as a Video Player, Music Player and Bestiary.

Cons:
- The Augment System: Making the game a bit more modern with customization is not a bad thing, but Final Fantasy IV Advance offered the usage of the near full roster of characters themselves towards the end of the game, as well as a new dungeon to trek through for proper end-game equipment for the new characters while the DS version only offers their abilities. This is a step backwards, though it will not matter much to those who have never played it before. Also, Augments can only be used once and must be used in order to acquire stronger powers from departing characters. Multiple playthroughs are required to offer a full selection of Augments.
