Players now have their own avatars and can explore portions of Domino City from the original Yu-Gi-Oh! series and the Duel Academy from the Yu-Gi-Oh! GX series. The dueling screen and the Deck editor have also been redesigned and improved. One of the latest improvements of this game are the NPCs. They exist in both Domino City and Duel Academy. (Yu-Gi-Oh!
