While at this point in video gaming you can only make a fireball look different in so many ways, where there are unique features they tend to stand out. In looking at other SE creations, I think I've noticed a few references to other games. We aren't counting other FF titles (including XI) and obviously there was a Dragon Quest crossover. But what about the following...

1. BLM eye-patch. Without spoilers, the BLM AF headpiece has an elaborate eyepatch that resembles one found on a character in Nier. Has anyone else gotten that feeling of similarity? There are many eye-patches in XIV, just none like this one which makes it stand out.

2. ARC casting. The red "swirly-square" animation on the book when casting resembles the seals that close off battle areas in Drakengard 3. It may be a stretch, but these battle areas often have crates in them to hide goods and as we know, ARCs work around crates all the time (let alone work with magic and such).
