The Active Time Battle System from the first Super Nintendo edition is still present in Final Fantasy IV. Maintain the same control input while enabling other players to use the Nintendo DS's unique touch control system. The control of the stylus is restricted and optional, similar to the earlier remake of Final Fantasy III on the Nintendo DS. The "Augment System," or "Decant Ability System" (Dekanto Abiriti Shisutemu) in the Japanese edition, is a new ability system introduced in the remake.

The mechanism enables the transfer of specific character-only abilities to other characters who did not possess them in the first and earlier re-releases of Final Fantasy IV. Temporary party members can inherit up to three commands. Temporary characters will leave the group with skills of their own, the number of which will depend on how many they were given.

The title's fourth entry in the FINAL FANTASY series debuted in 1991. It became wildly popular because of its distinctive characters and compelling plotlines and was ported to other platforms.

The Active Time Battle (ATB) system was initially included in FINAL FANTASY IV, which has come to be identified with the series. Additionally, the Augment system, which allowed characters' powers to be transferred and offered players an advantage in battles, was introduced during this time.

Setting

Most Final Fantasy IV is set on Earth, often known as the Blue Planet, which comprises an underground realm called the Underworld and a surface realm called the Overworld, home to Dwarves. The planet where the Lunarians reside has an artificial moon around it. The asteroid belt around the Blue Planet was formerly home to a species known as the Lunarians. The moon-shaped crest may recognise them on their foreheads. When they thought their species could coexist with humans, they built the artificial moon as a place to relax. Even though a second, natural moon also circles the Blue Planet, it is never seen in the Game.
