Clearly Meeko does NOT know Yu-Gi-Oh.
Yugi is not a title. It’s his name. Yugi Moto. (One of those 'o’s is long, I can’t remember offhand which it is.) Yami (short for Yami Yugi, or Dark Yugi) is occasionally used as though it’s his name, but that’s because he’s a different entity than Yugi, and saying Yami Yugi every time is a pain in the ass. When it’s revealed that he’s the legendary Pharoah, that’s used as though it’s his name, too. Because he has no other name.
In the cartoon many of the other characters are renamed, but Yugi’s intact, as are the Kaiba brothers. (FTR, Joey == Jonouchi, Tea == Anzu, and Tristan == Honda.)
Yu-Gi-Oh is not, in any way, connected to WotC. It’s not licenced from or by WotC, or any other division of Hasbro. I can’t even figure out where you would have gotten that idea.
Granted, Magic is a likely inspiration for Wizards and Monsters/Duel Monsters. But it’s more the CCG genre in general - it’s not like M:tG has been the only one on the market for a long, long time. The mechanics of the game are completely different, aside creatures having both an attack and defense score - and those scores function completely differently. Magic is Poker to Yu-Gi-Oh’s Old Maid. A more complex game, aimed at an older audience, with completely different rules, aside from the parts that are common to all card games, and some genre cliches. This holds even more true for the unplayably simple version of the game that was originally introduced early in the manga, before they realised it would be popular enough to licence.
And ‘Collectable Card Game’ is too general an idea for WotC to own. So any attempt by WotC to claim ownership would fail horribly - it’s not like Kodansha and Konami are small companies that can be burried by Hasbro’s legal team even if there’s no case there. So, Konami didn’t licence it from WotC, and Topps licenced it from Konami.
(BTW, bodypoet - that’s Swords of Revealing Light. A delightful card to have, a bitch to have played against you.)
Man…that was a LOT of writing about Yu-Gi-Oh, of all things.
