Final Fantasy IV

Final Fantasy IV (also known as Final Fantasy II for its initial North American release) is a role-playing video game developed and published by Square (now Square Enix) for the Super Nintendo Entertainment System. Released in 1991, it is the fourth main installment of the Final Fantasy series. The game's story follows Cecil, a dark knight, as he tries to prevent the sorcerer Golbez from seizing powerful crystals and destroying the world. He is joined on this quest by a frequently changing group of allies. Final Fantasy IV introduced innovations that became staples of the Final Fantasy series and role-playing games in general. Its 'Active Time Battle' system was used in five subsequent Final Fantasy games, and unlike prior games in the series, IV gave each character their own unchangeable character class.

Final Fantasy IV has been ported to several other platforms with varying differences. An enhanced remake, also called Final Fantasy IV, with 3D graphics was released for the Nintendo DS in 2007 and 2008. The game was re-titled Final Fantasy II during its initial release outside Japan as the original Final Fantasy II and Final Fantasy III had not been released outside Japan at the time. However, later localizations used the original title.

In Final Fantasy IV, the player controls a large cast of characters and completes quests to advance the story. Characters move and interact with people and enemies on a field map, which may represent a variety of settings, such as towers, caves, and forests. Travel between areas occurs on a world map. The player can use towns to replenish strength, buy equipment, and discover clues about their next destination. Conversely, the player fights monsters at random intervals on the world map and in dungeons. In battle, the player has the option to fight, use magic or an item, retreat, change character positions, parry, or pause. Certain characters have special abilities. The game was the first in the series to allow the player to control up to five characters in their party; previous games had limited the party to four.

Player characters and monsters have hit points (HP), with the characters' HP captioned below the main battle screen. Attacks reduce remaining HP until none are left, at which point the character faints or the monster dies. If all characters are defeated, the game must be restored from a saved game file. The player can restore the characters' hit points by having them sleep in an inn or use items in the party's inventory, such as potions, as well as using healing magic spells. Equipment (such as swords and armor) bought in towns or found in dungeons can be used to increase damage inflicted on monsters or minimize damage received. The player can choose whether characters appear on the front line of a battle or in the back. A character's placement impacts damage received and inflicted depending on the type of attack.

Final Fantasy IV introduced Square's Active Time Battle (ATB) system, which differed from the turn-based designs of previous RPGs. The ATB system centers on the player inputting orders for the characters in real time during battles. The system was used in many subsequent Square games.

Each character has certain strengths and weaknesses; for instance, a strong magic user may have low defense, while a physical fighter may have low agility. Like other Final Fantasy games, characters gain new, more powerful abilities with battle experience. Magic is classified as either 'White' for healing and support; 'Black' for offense; or 'Summon' (or 'call') for summoning monsters to attack or carry out specialized tasks. A fourth type, 'Ninjutsu,' consists of support and offensive magic and is available to only one character. Magic users, who account for eight of the twelve playable characters, gain magic spells at preprogrammed experience levels or fixed story events. The game includes balanced point gains, items, and rewards to eliminate long sessions of grinding. Due to the Super NES' greater processing power, Final Fantasy IV contains improved graphics when compared to previous Final Fantasy titles, all of which were released on the NES. The game employs the Super NES' Mode 7 technology to give enhanced magic spell visuals and to make airship travel more dramatic by scaling and tilting the ground for a bird's eye view.
