Introduce a whole lot of tribute to the best final fantasy game, Final Fantasy Tactic

[Enkidoh]

Do you have a source for that? It was my understanding that FFXII's story actually comes first in the Ivalice timeline - and that FFT was set in Ivalice's far future (for instance, in FFT it was stated that moogles were long extinct, hence the Moogle summon, and how Ivalice had reverted to a neo-medieval existence, with relics from a technologically advanced civilization being unearthed.) Not to mention Balthier turning up in FFT (the PSP remake) in a chronological appearance that took place after FFXII. But anyway, I digress.

Getting back on track, there are actually already quite a few Ivalice Alliance/FFT references in ARR already - the Corpse Brigade and their leader Millounde springs to mind for example. Then there's the names of the Ascians being the same as the Scions of Light from FFXII (not to mention Belias appears in the final SMN Job quest, and

Zodiark

is revealed to be the name of the Ascians' 'one true god' whom they're trying to revive. And who can forget Ungust's outburst channeling Delita's famous "blame yourselves or God" line from FFT?

There are plenty of FFT/FFXII references already in ARR, you just have to open your eyes and look for them.
