Besides the radical addition of the ability to customize your party, several other minor gameplay tweaks have been made. The characters in your party now share their thoughts with you on the menu screen, offering personal anecdotes and potentially helpful advice about the current situation. An entirely new quest line featuring Namingway--a moogle-like wanderer who in the original version was satisfied with renaming your characters when asked to--has been added, in which Namingway renames himself as he tries out a number of different professions with humorous results. Finally, Rydia receives a unique new Eidolon named Whyt that can be completely customized by conversing with Fat Chocobo, who fans will likely remember as a bank for extra-item storage (that service is no longer necessary because the item cap has been removed). Through Fat Chocobo, you can customize Whyt's appearance, assign him an assortment of attacks, level up his various stats by participating in touch-screen-heavy minigames, and even battle your friend's incarnations of Whyt in one-on-one matches via local DS wireless.
However, outside of Whyt's minigames, there isn't much going on with the touch screen. When not in battle, the bottom screen is occupied by an area map that automatically fills as you explore dungeons, and it's possible to navigate your party around the world by manipulating the stylus. At most other times, the touch screen is nonfunctional. Thankfully, the button controls are very effective, and so it's generally best to not even try to mess around with your stylus.
Final Fantasy IV is easily among the best-looking 3D games on the Nintendo DS. The heavily stylized characters are impressively expressive, from the manner in which Cecil broods as he reflects on his guilt to the way that Rydia hops up and down and waves her hands to get your attention at a shop when you find something that she can equip. Now that dungeons are rendered in three dimensions, there is a vast sense of size and depth (particularly in the final dungeon) that wasn't previously there, and it makes your journey seem that much more awe-inspiring and epic. As part of the new graphical update, key moments of the game are shown off in cinematic-style cutscenes, many of which are accompanied by full voice acting for the characters. Unfortunately, as excited as series fans may be to finally hear Cecil speak, the voice acting is actually the game's weakest point. Some voices seem completely out of character or introduce unnecessary melodrama.
Although it has been rereleased several times throughout the years, this full remake of one of the most celebrated stories in video game history is in many ways more poignant and impressive than it was all those years ago, despite minor irks with the voice acting. With a cast of memorable characters and villains, a more accurate and authentic translation, a new skill-customization system, and a few important new story elements that help to better explain key plot points, this is the definitive version of Final Fantasy IV that everyone should experience.
