(1.0) Near the end of the cutscene in which Gaius fights Thancred, Y'shtola, Yda, and Papalymo, the four Circle of Knowing members stand a distance from him in a small row. This could be a visual reference to how parties used to stand in rows in the first ten Final Fantasy games.

The 2013 All Saints Wake (Halloween) event features a Magic Pot NPC. It resembles the imps of Final Fantasy XI and Final Fantasy XIV hiding in the conventional urn. When players interact with it, it boasts that the Impressario gave it an Elixer and rocks backward gleefully.
Before most storyline battles, the common "whoosh" effect of previous games' random encounters is seen.
The Artifact Equipment for the Summoner job class is called the "Evoker's equipment" and the upgraded version is the "Summoner's equipment", alluded to the job Evoker and its upgraded version, the Summoner from Final Fantasy III.
The Crystal Towerdungeon is directly inspired by the Crystal Tower from Final Fantasy III. It is said that the tower houses the tomb of the first Allagan emperor, named Xandes, whose name is influenced by an antagonist from Final Fantasy III, Xande. The dungeon is also home to various bosses that are homages to Final Fantasy III enemies, the Cloud of Darkness among them. The theme Altar Cave and Battle 2 have been rearranged for this dungeon.
The Onion Helm is a helmet available to players who purchased the Collectors Edition of the original game, the rest of the Onion Equipment is available as prizes in the Crystal Tower.

Although not written in the dialogue, Minfilia speaks to a person, named Krile, via linkpearl in an underlain audio, after the Scions reunite and escape Castrum Centri together.

(1.0) During the 2011 All Saints Wake (Halloween) event, the trickster imps would randomly say "Life... Dreams... Imps... Where do they come from? And where do they go?" upon spawning, quoting Kefka's speech during the final battle of Final Fantasy VI.
The Garlean Empire technology is called magitek, and has advanced considerably due to the works of a Cid and is primarily used for military purposes. Additionally, a Magitek Armor mount is available to players.
The first video showing the Magitek Armor in-game was a short re-creation of the opening to Final Fantasy VI, with a green haired female hyur and two other characters riding the Magitek Armor in a snowy region, and a remix of "Terra's Theme" playing in the background.
The 2013 All Saints Wake (Halloween) event features a circus troupe led by a man simply named "The Impressario", alluding to an NPC of the same name in the Opera House.

(1.0) When the player undergoes his first "Horn & Hand" faction leve, a NPC will say the following: "Why, if it isn't Sephiroth! Or was it Sephiross? Setirophx? xXxSephirothxXx?", referencing Sephiroth and common variations used to name characters on MMOs (and by proxy, Final Fantasy XIV itself - although of comical note is due to the game's naming conventions, many such variations are not possible).
(1.0) An NPC in the Miner quests will mistakenly call players by the wrong name. He will call a Midlander Hyur "Cloud", and a Miqo'te "Aerith".
(1.0) There are two references to main antagonist Sephiroth, both of which are made by main antagonist Nael Van Darnus (and might explain why he is designated the Legatus of the VIIth Legion):
In "United We Stand," after wounding the player, Nael takes his leave similarly to that of Sephiroth in the Nibelheim burning scene.
Nael seeks to destroy Eorzea and subsequently purify it by using forbidden magicks to summon the Meteor-like moon Dalamud. Sephiroth similarly attempts to destroy Gaia by using the Black Materia to summon Meteor in Final Fantasy VII. Both do so because they feel it is their birthright and duty.
One of the Cactuar enemies is called Sabotender Del Sol after the location Costa del Sol.
During the 2014 Heavensturn (New Year) event, during the year of the horse, an argument between the Chief "Chocowhacker" and the far eastern Uma Bugyo contains the following line: "As for your precious horses, they're just unicorns with a big empty forehead! Hornless! Hornless!". This alludes to Biran and Yenke Ronsos' mocking of Kimahri Ronso for his broken horn.
(1.0) Two of the Achievement NPCs bear the last name of "Ironheart", a reference to the famous cartographer Gwynham Ironheart. They are Milith Ironheart (in charge of Dungeons) and Nedrick Ironheart (in charge of Exploration). Nedrick is still present as the quest giver for various dungeons apart from the main story, such as the Sunken Temple of Qarn and Amdapor Keep.
(1.0) The NPC responsible for unlocking the battle category of achievements is named Atelloune, sharing her name with a minor NPC present in Final Fantasy XI. Both of them are researching monsters, wear the exact same outfit and are of similar races (Elvaan/Elezen).
All of the playable races are derived from the Final Fantasy XI races, although there are enough differences that they are likely not connected (namely the female Roegadyn).
Several beast tribes, namely the Qiqirn, Mamool Ja, Gigas, and Goblins, are upscaled versions of their Final Fantasy XI models. Many other monsters are taken from Final FantasyXI, XII, and XIII.
The original beastmen from 1.0 were likely derived from XI's beastmen as well. The Ixal are flightless birds like the Yagudo, the Amalj'aa strongly resemble Mamool Ja, and the Kobolds are reminiscent of Goblins (or more specifically their subterranean brethren, the Moblins). Goblins and Mamool Ja were not introduced until long after 1.0's release.
The Primal, Garuda strongly resembles the design for Final Fantasy XI's Garuda in that she is a pale green winged woman.

Members of the Ascians, who worship Zodiark, are named after the Scions of Light that were mentioned in profiles on the Espers.
Some of the Pulse/Ancient Automata-type enemies are reused as enemies in A Realm Reborn. The Beta Behemoth enemy is also brought into the game during the Lightning Strikes storyline.

Lightning and Snow's hairstyles are available for player characters after finishing Lightning Strikes event and "Beauty Is Only Scalp Deep" sidequest.
Jandelaine the aesthetician NPC, begins his service by turning a female Lalafell's hair into Lightning's hairstyle.
In the quest "Rolling With The Snowies in Coerthas Central Highlands, the snowman says "Revolutionaries always get called crazy." The same line was used by Fang in Final Fantasy XIII.

In one quest, there's line uttered by the cowardly merchant, Ungust, that quotes, "Spare me your contempt! If you want to blame someone for the mess the world's in, blame yourselves or the gods!" A line Delita Heiral says in the beginning of the PS version of Final Fantasy Tactics to Princess Ovelia Atkascha. (It was changed to "'Tis your birth and faith that wrong you... not I" in the War of the Lions version),
The dark deity Zodiark is represented by a character called Elidibus, who was clearly named after an optional superboss fought at the bottom of the Midlight's Deep; Zodiark appeared in this game as a summon used in battle by Elidibus, who was implied to have pledged his soul to the dark being.

The titles of the two FATE's for the Behemoth battle, "Behold Now Behemoth" and "He Taketh It with His Eyes", are both quotes describing the behemoth from the Book of Job in the Bible: Job 40:15 and Job 40:24 respectively.
While the Roegadyne's Sea Wolves and Hellsguard seem to correspond to the frost giants and fire giants, the Elezens' Wildwood and Duskwight branches are respectively based on the Light Elves (Ljosalfr) and the Dark Elves (Dókkalfr).
Jehantel of the Bard quests speaks the line "You would know why I truly abandoned the battlefield and became a bard? That I took an arrow to the knee is what most folk believe...", a reference to the infamous Skyrim NPC line "I used to be an adventurer like you, then I took an arrow to the knee".

One of the Botanist levequest is called "Shaken, Not Stirred". It's a catchphrase of Ian Fleming's fictional British Secret Service agent James Bond, and his preference for how he wished his martini prepared. It was first uttered in the films by Sean Connery in Goldfinger in 1964.
A FATE in the Black Shroud featuring a pack of invading Anoles, which are velociraptor-type monsters, is titled "Clever Girls". This is a reference to a famous line spoken by the park's game warden Robert Muldoon just before being out-maneuvered by velociraptors in the first Jurassic Park movie.
