Not every card, some cards aren't in and cards that are TCG exclusive aren't in there like Charge of The Light Brigade. However they do have OCG exclusive cards like all the duel terminal sets. The game also doesn't have raging battle, so if you were planning on using anything from that set, like blackwings, it's not there. Also for blackwings, they only have Gale, Bora, and Sirroco. Other than that stuff, almost every card is in the game, only a few ones aren't.
Hey, Parasite, there've been some changes to the layout of my Yu-Gi-Oh WC 2008 Club, the main thing being a new rank system where you have to put a ribbon in your sig and optionally put the rank under the ribbon in your sig, that is all, go check it out to get up to date, it'll be in the first post.
