The story follows siblings Lann and Reynn, who possess the power to tame monsters called Mirages, and are sent to Grymoire to reclaim their lost memories and thwart the plans of the Bahamutian Army.

Development started around the concept of a Final Fantasy title aimed at a wider and younger audience, focusing on a light tone and stylized graphics compared to the mainline entries.

First announced at the 2015 Electronic Entertainment Expo, World of Final Fantasy was intended as a celebratory title to commemorate the series' 30th anniversary.

Reception of the game was generally positive, with many praising its aesthetics and stacking mechanic, but criticism focusing on its slow pace and storyline.

[8][3][9] Another action accessed from Nine Wood Hills are Intervention Quests, storylines ending in boss fights focusing around character cameos from parts of the Final Fantasy series.

A notable addition are Champion Mirajewels, items that allow Lann and Reynn to transform into chibi versions of Final Fantasy protagonist and gain access to unique abilities.

With help from another Exnine Knight using the "Masked Woman" as a puppet, Brandelis manipulated the twins into reopening the Ultima Gate, allowing a parasitic race called Cogna to begin consuming Grymoire.

Lann, Reynn and Hauyn together with the summoners and their champions then launch a united attack and successfully reverse the Ultima Gate, pulling the Cogna from Grymoire.

A secret ending added in Maxima has Hauyn fighting a Diabolos mirage from another world, while an older and ragged Lann continues to search for a missing Reynn.

[1][26] The initial concept for World of Final Fantasy was created between series producer Shinji Hashimoto, and Square Enix staff member Hiroki Chiba.

[1] The scenario was written by Chiba, whose main focus was to create a story that would appealed to young players with comic dialogue, while keeping true to the characters drawn from each Final Fantasy title.

[8][11][27] Alongside the main narrative, Chiba wrote a novel's worth of additional side content found in optional books and leaflets to add context to the game's world.

[11] Numerous guest artists contributed Mirage and character designs including Yūsuke Kozaki, Yuji Himukai, Shirow Miwa, Yusuke Iwasa, Ryota Murayama and Taiki.

[35] The initial idea for the protagonists was for them to share the chibi art design of the rest of the cast, but Chiba felt that this would weaken the game as it did not represent the "sweet and sour" aspects of the series.

[37] The game's soundtrack was primarily composed and arranged by Masashi Hamauzu, with other contributions from Shingo Kataoka, Hayata Takeda, and Takashi Honda, consisting of nearly one hundred tracks.

[39] Vocals for the soundtrack were performed by Mina Sakai, a vocalist who had worked with Hamauzu on Final Fantasy XIII and formed part of his musical group Imeruat.

[40] Chiba wanted a composer who was synonymous with the Final Fantasy series, and although he initially considered Nobuo Uematsu, he settled on Hamauzu due to an earlier positive working relationship between them.

[38] Hamauzu's work was the subject of constant oversight, with other leading staff making sure his music fitted different scenes, and requesting changes when they did not; this checking was motivated by the wish to pay respect to the original characters.

[44] The bad ending theme, "Silent World", was composed by Ryusuke Fujioka and sung by Tama's voice actress Ayana Taketatsu.

[42] The true ending theme, titled "World Parade", was composed by Ryo Shirasawa of Noisycroak and performed by Taketatsu, Kana Hanazawa (Enna Kros) and Eri Kitamura (Serafie).

[47] The port featured limited graphics options and was locked to thirty frames per second, but came with several cheats including free AP, max money and items, and disabling random encounters.

[14] In the West, several editions were created outside the standard original release; all versions featured in-game extras of additional mirages and the Japanese dub.

[49] Final Fantasy VII antagonist Sephiroth was included in first print copies in Japan, and as part of the special editions in the West.

[37] The original game received limited-time downloadable content (DLC) later that year giving players a Champion Medal summon of Sora, lead protagonist of the Kingdom Hearts series.

[56] World of Final Fantasy Maxima is an expanded version of the original game, released worldwide on November 6, 2018, for Nintendo Switch, Xbox One, PS4 and Windows.

Final Fantasy XV protagonist Noctis Lucis Caelum appears as part of a fishing minigame and as a Champion Mirajewel.

[58] Tose returned to develop Maxima along with Square Enix's Business Division 3, and the game used the latest version of the Orochi engine.

[60] Chiba considered creating a dedicated scenario, but decided upon a fishing minigame following the release of the spin-off title Monster of the Deep.

[61][62] Meghan Sullivan of IGN wrote: "World of Final Fantasy is a humorous adventure that is just too cute for words, but its combat and exploration aren't diverse enough to support a campaign nearly as long as this one.

If you're willing to put up with some of the game's mundane sequences, you'll get some enjoyment out of it, but if you're not a Final Fantasy fanatic, the magic in these moments may be lost altogether".
