Final Fantasy I and II Changes and Additions-Game Boy Advance

A battle against a Soul of Chaos boss in the GBA version. This one is Shinryuu from Final Fantasy V

Both games were faithful in content to the original NES versions, and the package, while graphically similar to the WonderSwan Color adaptation of the first game, also contains the Bestiary feature, which allowed the player to view images and statistics of enemies that they had defeated in both games, and which first featured in the PlayStation package.
However, the package lacked the ability to choose between easy and normal games as was available in Final Fantasy Origins, although not in the original. Many reviewers complained that the first game appeared to default to "easy", making the heroes level-up much more easily and rendering enemies much easier to defeat, especially in comparison with the NES original. Many items were cheaper, the party began with more money, and defeating enemies brought greater rewards. Others praised the reduced difficulty level, saying that the high difficulty level (especially in comparison to later titles) was its primary weakness. In Final Fantasy II, magic degrading as physical strength grew and vice versa was removed; unlike the changes to Final Fantasy I however this was generally better received among players. Another thing that was added to both games is the ability to save the game at any point out of battle, and later resume from that same point, while the originals only allowed this under certain conditions. This was not a feature in Final Fantasy Origins or the original versions of the games.
Final Fantasy I also featured four extra dungeons known as the "Soul of Chaos" dungeons. These dungeons are accessible by restoring power to the Crystals by defeating each of the Elemental Fiends; the death of each Fiend unlocks a dungeon terminating in a selection of four bosses each from Final Fantasy III, IV, V, and VI.
Final Fantasy II featured a completely original feature found in none of the previous remakes. Once completed, a bonus storyline entitled Soul of Rebirth would be accessible to the player, featuring a number of characters who had been killed off during the course of the main story. The game only features four areas and most of the time will be spent training up for a second encounter with the last boss. An Ultima tome can be achieved but it requires the killing of the extremely powerful Ultima Weapon.
Additionally, the airship parts in both use Mode 7.
