Far as I can tell it's just real' good recreations of places and duelists with all them fancy Kaibacorp computers. I'm in da game for example, but it's da me from around Duelist Kingdom and Battle City. They got da Rare Huntah guy Marik's sister Ishizu in der' too, but it's a version a' her from back when she still had da' Millennium Necklace. All the folks from da present are people, but you can step back in time too and that's all kinds-a cool. I've even had duels against myself and, boy, I sure kicked old me's butt!
