Final Fantasy IV is the compelling story of a man who has to betray his king to do the right thing. As Cecil the Dark Knight struggles to find redemption for the sins he has committed under the command of King Baron, he reveals to all the light hidden within him. There are more secrets for Cecil to discover about the world he lives in- and himself. The other characters add fun, humour, and real emotion to this Final Fantasy epic. In my mind, it's still the best storyline out of all the classics (FF1-6).
As for the DS remake...
The DS remake keeps all the classic Final Fantasy elements whilst giving you something new and exciting. For one thing there's the adorable character graphics. The new 3D characters make every thing seem bigger- especially during the cut scenes. Cecil's "transformation" scene was awesome. And though the voices are grainy- I think that's fine considering all the other improvements.
The best thing they've added to this game is "Whyt", Rydia's new Eidolon. Not him specifically- but the way you level up his attributes. The DS game takes advantage of the touch screen capabilities with enormously fun mini games. Depending on who you have in your party, the mini games change. You can play "Cecil's Goblin Gauntlet" or "Rosa's Time Challenge" and many others. They're all fun games testing your reaction times and your maths- but it's not too difficult that children couldn't do it too.
Whyt can be 'decorated' in different ways using the touch screen too. There's a lot more to do besides the main story now. One thing I find funny about this game are the dancers. If you talk to all the dancers in different towns and watch them perform, and then go back to the town near Baron- Cecil will dance with the girl near the river. It's hilarious!
The music is still top notch- as are the battles. I like the victory dance after every win even more now. I like that when you go into a shop, characters pose in their own relaxed manner and then wave, put up their hands or jump to let you know they can use that piece of armour.
Namingway also has a bigger role in the remake. He changes his own name this time, as he struggles to find his perfect career. Each "career" gives you something great to do. When he decides he wants to try something new, he hands the task down to his friend- Fat Chocobo. You can access all the music from the game to listen to; play Whyt's mini-games and view all the major cut scenes again. In order to activate these additions and extra features, you must make sure you keep looking for and talking to Namingway in every town and village you go to. He's even in a couple of castles and dungeons too.
Basically, Final Fantasy IV was an epic game before the DS remake. And it's been made even better! I didn't think that was possible! Buy it if you love RPGs!
