This "2005" World Championship Tournament edition of Yu-Gi-Oh for GBA presents single-player duelists with a wealth of virtual card-battling options. A small town full of dozens of potential adversaries serves as the game's setting, and through a simple RPG-style interface players can meet other characters, enter duels, earn new cards, and learn new techniques. As the game is played, more and more cards are unlocked, and 200 cards new to the franchise debut in this release. Unlike the previous year's edition of the title, 7 Trials to Glory lets players build and maintain as many as 20 separate decks, allowing them to customize their cards for different dueling techniques or design special decks for battles against particularly challenging individual opponents. Head-to-head duels between two cartridge-equipped players are supported through a link cable connection. First-run retail versions of Yu-Gi-Oh!: 7 Trials to Glory -- World Championship Tournament Edition 2005 come packaged with three "Limited Edition Official Game Cards." ~ T.J. Deci, All Game Guide
