As well, an AI opponent will Tribute Summon as soon as possible, even tributing 1 monster to summon exactly the same monster, or even a weaker monster than the original. The AI is rather poor: if a player has a face-down monster with 2000 defense points, and the AI opponent has a monster with 1900 attack points, they will not attack as they "know" they cannot defeat the face-down monster. For example, Simon the Exodia duelist has three of each of the Exodia parts in his deck, where normally a player may only have one. However, the stronger duelists don't follow the Limited list either. When a duelist has at least one copy of all 1,138 cards, they can choose to ignore the Limited List. Each opponent has different skills and decks revolve around a certain theme (Yugi=Basic, Exodia Rare Hunter=Exodia, Yami Yugi (Dark Yugi)=Ultimate, etc.). There are 29 opponents in the game, however duelist 29 can't be played and is locked when Marik is at least once defeated. The game features the first 1,138 cards released in Japan. The player can assemble a deck and can duel against a variety of computer opponents. The duel system is almost exactly the same, but there are a few differences. This game has many obvious similarities to The Eternal Duelist Soul.
