Tetsuya Nomura explained that the Buster Sword was redesigned in Crisis Core Reunion to be more in line with Final Fantasy 7 Remake.
Since Crisis Core Reunion was unveiled last month, there have been several questions about whether it’s a remake or a remaster, with Square Enix’s responses suggesting it falls somewhere in between. One curious change that could be seen in the first seconds after the announcement of Crisis Core Reunion is that the Buster Sword has been redesigned to match the design of Final Fantasy 7 Remake.
This immediately sparked theories that Crisis Core Reunion would change the game’s ending in some way, and that the fact that the sword is different is a sign that it will have something to do with Final Fantasy 7 Rebirth. Subsequently, Nomura clarified in an interview with Gamespot that this was done simply so that the game would not differ from Final Fantasy 7 Remake.
The design of the Buster Sword in Crisis Core was originally based on that of Advent Children, however this time the sword design will be based on Final Fantasy 7 Remake, just to make sure that Crisis Core Reunion matches Final Fantasy 7 Remake and there are no discrepancies in the design. Since the remake is based on the original Final Fantasy 7, we wanted it all to be consistent.
This explanation also seems to fit with the fact that Nomura has stated that Crisis Core Reunion will not feature any changes to the Crisis Core storyline.
As Final Fantasy fans no doubt know, this isn’t the first time the Buster Sword has been redesigned. The original version used in Final Fantasy 7 was much more simplified and had only one color on the blade. The second design, used in Crisis Core and Advent Children, is much more intricate, with a stylized gold handle that sort of splits into two shades for the blade. Finally, for Final Fantasy 7 Remake, the blade has been redesigned, combining elements of the two previous designs into one, as well as adding some of its own details.
