How would you like old FF's to be referenced? Personally I'm hugely against in your face references to characters or places that have no logical place on Hydalen.
One reference I really like is:
The Onion Doublet Set [FFIII counterpart]
Notice how this set references the original armour heavily? (here's a more recent iteration if you're not convinced)
This is how I want all armour to be referenced in ARR. It's not OTT, it has a logical place in the XIV lore and it's been made to fit into the aesthetic views of XIV, making it feel like it's supposed to be there.
If a player who has never experienced the series can't see that a certain set of armour is looking significantly weird, compared to rest then I think that SE has done a good job.
There's a couple of other references I enjoy like the whole Sephiroth/mocking name reference. too.
There's already a number of other references to VII.
So how do you think XIV should reference the older games?
