That sounds so cool, piloting a giant robot! [She's totally jealous. Why doesn't her world have that?]

[Then she remembers the damage that cards and holograms can do, so it's probably a good thing there aren't gigantic robots in her world yet. Better get on that, Kaiba.]

[Still thinks it would be really cool to at least see it.]

It's called Duel Monsters. It's... a card game that uses different monsters and magic cards and traps to defeat your opponent's monsters and such.

It's... actually kind of a long story with one thing leading to another; from defeating the reigning champion at the time to defeating the game's creator, it... sort of gave me the title of 'Queen of Games.'
