List of Final Fantasy references in A Realm Reborn

[AmnesiaHaze]

reference to the legendary:

[Zantetsuken]

Minfilia refrences "Krile" (the name of a FFV char) in the last scene of the 2.1 main storyline IIRC.

[Lukahn]

In the first post it mentions Umaro is in XIV? Where?

[Tiggy]

Final Fantasy 7:

The bar in Revanant's Toll where the Scions new base is located is called "Seventh Heaven." Also, as in FF7, the bar holds a secret base.

[Nekome-sensei]

Enemies from Binding Coil of Bahamut turn 4 - Clockwork soldiers/knights use the same model as enemies from ff13 Pulsework soldiers/knights, same goes for Clockwork Dreadnoughts.

Name of the head of Goldsmith guild - Serendipity is the name of casino from FF-13-2

[Lucarius]

As I was 90k'ing with impending server patch coming up, I realized that Coil Turn 4 takes place in the "Ragnarok Drive Cylinder," which seems like an FFVIII reference.

[Alice_89th]

Name of the head of Goldsmith guild - Serendipity is the name of casino from FF-13-2

While they are indeed the same, I am not entirely sure it is a reference. Serendipity is an existing word, and it matches her personality pretty well.　Also, Serendipity (the casino) is called ザナドゥ (Xanadu) in the Japanese version :/

[RoughDivider]

Death penalty is also the name of Vincent valentines weapon from FF7. Also Squall's from FF8 facial scar is an option for hyur mid landers.

[Vizarie]

not sure if people mentioned this

the seventh heaven in revnants toll is named after the one in FF7 it also has a "secret base" though without the lift that goes down

The current FFXI-crossover event 'Burgeoning Dread' naturally features a ton of references and in-jokes to, FFXI: (Possible spoilers for those who haven't done the event yet)

The FFXI crossover event in ARR revolves around Shantotto, a tarutaru BLM and the former Minister for the Orastery, one of the five ministries of magic, in the Federation of Windurst in FFXI.
Instead of the usual ARR style font for the 'quest accepted/completed, FATE Joined/Complete' titles, the FFXI event quest instead uses the actual FFXI game logo and traditional FF font.
The FFXI crossover event is both started and completed in Gridania, a similar nation to Windurst where Shantotto hails from (a nation of mages who revere nature).
The sound effect that plays upon completing both the second Shantotto FATE 'Tower of Power' and the actual quest itself, is the short fanfare (arranged by Naoshi Mizuta), that plays in FFXI when a player completes a quest.
The battle theme for the second Shantotto FATE 'Tower of Power' is Feast of the Ladies by Naoshi Mizuta, the final boss theme against Domina Shantotto and Belle Shantotto from the FFXI A Shantotto Ascension mini-expansion.
Shantotto uses traditional powerful (tier IV) FFXI black magic spells that aren't available to the player in FFXIV, such as Firaga V, Blizzaga V, Tornado II and Gravity II in her FATE 'Tower of Power.'
One of Shantotto's attacks in 'Tower of Power' is 'Play Rough', the name of her EX Burst attack in Dissidia Final Fantasy and Dissidia Duodecium 012 Final Fantasy.
The weapon Shantotto wields in battle in Tower of Power is the Fire Staff, a level 51 weapon in FFXI available to all mage jobs - Shantotto also wielded this weapon in her Dissidia appearances.
The equipment Shantotto is wearing is Tactician Magican's gear, level 50ish 'Conquest' mage gear for Windurst that is available to players in FFXI (it's the same outfit she actually wears in FFXI)
During the end cutscene for the FFXI event, the giant Shantotto that the player fought is revealed to be nothing but a doll that the real Shantotto had magically enlarged - this is a reference to a special event battle in FFXI where the player can fight various female NPCs, including Shantotto. Shantotto's appearance in that event was revealed to actually have been a doll that the real Shantotto was controlling (this is also referenced in Dissidia).
During the end cutscene for the FFXI event, Shantotto mentions she comes from "The Federation of Windurst in the world of Vana'diel", which is indeed her home town and the name of the world of FFXI.
During the end cutscene for the FFXI event, Shantotto name drops the title for the FFXI mini-expansion that she has a staring role in, A Shantotto Ascension, the plot for which dealt with Shantotto accidentally casting a transdimensional spell which sends her across dimensions and starts the expansion's storyline that she also references in the cutscene as to the means of how she arrived in Hydaelyn. Her eyes even glow red momentarily like the 'Shantotto clones' in that expansion.

There's probably more, but this is everything I picked up on (as a FFXI player for over 9 years now).
