List of Final Fantasy references in A Realm Reborn

[Gwaeron]

Good King Moggle Mog XII keeps spamming "Mog Creation". Yuffie's limit break is called all creation, and looks the same.

All other moogles in the same fight have obvious references to FFXI (and often other FF) jobs/abilities.

In the original Mor Dhona you could see "mako reactors" (likely what is now called ceruleum processing plants), and the music themes in the zones were clearly references to FFVII. Compare http://www.youtube.com/watch?v=5SUtVOsacNE&t=165 (FFXIV) to http://www.youtube.com/watch?v=nswfLcROs-0 (FFVII)

The battle theme was pretty similar to Bombing Mission from FFVII, too, but maybe the reference isn't as clear. http://www.youtube.com/watch?v=3q9yZP7hu8M&t=40

It has Final Fantasy in the title like some of the other games. Some people dont notice that

During the conclusion of the bizarre Heavensturn event, one of the characters calls horses "Hornless! Hornless!" - A quote from Final Fantasy X, when Biran and Yenke Ronso are insulting Kimahri

[Nikoshae]

In FFXII you eventually go to Pharos at Ridorana, a building similar in appearance to a lighthouse. It is located on an island in the Ridorana Cataract, a place overlooking a huge hole in the ocean. The FFXIV dungeon Pharos Sirius is a lighthouse.

FFXI:

*3 FATEs feature the more infamous Morbol NMs in XI, Voluptuous Vivian (V for Vinedetta, Fogfens), Capricious Cassie (The Squirrel Trapper's Wife, Larkscall), and Jaded Jody (My Baby Green, Hopeseed Pond).

Pharos is another word for lighthouse, so this isn't necessarily a Final Fantasy reference.

Today I tried feeding and elixer to one of the pots in crystal tower, and it reacted by wobbling back and forth. Needs confirmation though

A little bit something from the 2.1 Hildibrand Quest:

At the end of the 2.1 Hildibrand Quest Chain, you see Gilgamesh defeating someone in a duel. When he collects their weapon, he exclaims "This is far from the strongest of swords!" This is a reference to when Gilgamesh found and later attempted to use Excalipoor against Bartz and crew during combat, before he is whisked away into the Rift for the first time by Exdeath. He also used this same phrase in Dissidia 012 when using his EX Burst and selecting Excalipoor from the weapon roulette rather than Excalibur.

In a preview of the next part of the Hildibrand quest chain (which will supposedly be added in 2.2), Gilgamesh is standing on top of a huge bridge in Eastern Thanalan, northeast of Camp Drybone. This will most likely end up being where Gilgamesh is fought, referencing a recurring theme that Gilgamesh's fights sometimes take place on bridges, and Gilgamesh's unique battle theme, "Clash on the Big Bridge".

Something to add to the list:

The Active Help window which explains the Search Window shows a sample search which includes several names of Final Fantasy Crystal Chronicles: Ring of Fates and Echoes of Time characters, as well as Kain Highwind (FF4), and Hurdy (FFTA2)

The FFCC:RoF names include: Cu Chaspel (one of the antagonists), and Meeth Crym, one of the four main party memebers.
The FFCC:EoT names include: Koo El and Del Dee (Optional characters that can be unlocked in the game)
There is also Sol Racht from the original FFCC.

Also the Summoner AF/2 makes you highly resemble a member of the Yuke race from the FFCC series, what with the wings on the back. (Though some have told me that wings are part of the clothing worn by summoners in other FF titles as well)

however, it doesn't seem the OP has been updated in a while.
