Well, Viz has realeased Volume 10 of the Manga as a "test" Manga. If it sells well they probably will release the others. The Manga is 250 pages long about, which is pretty big. Is it worth your money?
The Manga is freakin hillarious. SO much as I would actually not reccomend reading this in class as you will probably burst out laughing. (Or, if your like me, your rember something hillarious in the middle of class and laugh out loud).
Viz also does a nice translation, it doesn't look like their were any visual edit. The scipt inserts some american jokes (Deseperate Trophy Wives), but alot of the jokes probably wouldn't translate well. Also they call Don Patch Poppa Rocks, which kinda bugs me and leaves me wondering why they changed it only in the english Manga, the dub of the show leaves it as Don Patch. Also Osiris is renamed Slifer the Sky Dragon. Only in the dialouge, the cards says its Japanese name (Since I believe in japan the card is always written with the english alphabet). No! I am not thinking of the wrong Manga, Yugi (drawn by Takahasi), pops out of Bo's head and summons Slifer! FREAKING AWESOME!
So go buy this Manga, cause the future of a american release depends on it. And if you don't, Serviceman will attack you! (Uh..whats that suppose to be anyway?)
