Eye of Judgment's game director, Kazuhito Miyaki, thinks the Eye Toy has more potential than the Wii Remote. Speaking to CVG, he explained that hardware itself is relatively meaningless--how you use it is what really matters.
In Eye of Judgment, the Eye Toy is used to summon monsters from cards it scans. It can also track the movement of those cards (like how far away it is from the camera, or how it's oriented) to maintain an appropriate position on the card for the summoned monster. When comparing that kind of motion sensing to the Wii Remote, Miyaki said:
I must admit, I'm extremely curious about Eye of Judgment. It may end up being nothing more than a well-executed gimmick, but its premise is inventive enough to make me want to find out more.
