Duelists return to their GBAs for more trading-card battle in Yu-Gi-Oh! World Championship Tournament 2004. Since this is the "official software" of the 2004 Yu-Gi-Oh! video game tournament, players who develop decks and practice play in this version of the game will have an opportunity to prove their Yu-Gi-Oh! skills in a sanctioned competition, scheduled for the summer of 2004. As in the previous release, Yu-Gi-Oh! Worldwide Edition: Stairway to the Destined Duel, an in-game text translator allows English-, Japanese-, French-, Spanish-, Italian- and German-speaking players to compete against one another in their own languages.
Though following the basic design of earlier releases, Tournament 2004 features an unprecedented 1,100-plus virtual cards, including over 100 that are new to the franchise. The single-player game offers opportunities to duel against more than two dozen characters from the popular Yu-Gi-Oh! comic books and animated television series, all boasting improved AI over the computer opponents featured in past versions. Initial releases of World Championship Tournament 2004 come packaged with three actual, limited edition Yu-Gi-Oh! Cards.
