Eden has only appeared in FF8 prior to this as well, and it was a Guardian Force in that game, not a Sin Eater. It also couldn't cause a Flood of Light—that was from Final Fantasy 3's lore, not 8's. And quite a few of Return to Ivalice's settings only ever appeared in Tactics and 12—just either, not both—yet are so vastly different from each other that the reference is strictly superficial.
Hell, Ivalice in XIV is a nation that rose in fell so long ago that it's considered a myth, with uncovering the truth of its existence being one of the plot threads in the Return to Ivalice raids. The country the Return to Ivalice raids take place in isn't named Ivalice—It's Dalmasca. The continent isn't named Ivalice, either—it's Othard, the same continent that Doma, the Azim Steppe, and Valnain are on. The world isn't named Ivalice, either—it's somewhat amusingly named Hydaelyn.
So... Ivalice isn't Ivalice. Hell, half the Viera are from the Skatay Range, and last I checked that's not from Ivalice at all.
