Last month, Dragon Quest creator Yuji Horii revealed that he wanted to include the “Spell of Restoration” password system from the first two games in the series in Dragon Quest XI. At the time, it was unclear what role this password system would play in the game, but now it appears that it could be used to connect the 3DS and PS4 versions of the game. At Square Enix’s annual shareholders meeting yesterday, Yu Miyake stated that the Spell of Restoration could be used to allow saves to be transferred between the 3DS and PS4 versions of the game.
