An interesting fact about this game was that 3 separate versions of this game were released at the same time.

They each had their own cover (all 3 covers were similar though) and a different but similar name (Yu-Gi-Oh! Duel Monsters 4: Yugi Deck, Yu-Gi-Oh! Duel Monsters 4: Kaiba Deck, and Yu-Gi-Oh! Duel Monsters 4: Jounouchi Deck)

A characters respective cover had them up front with the other 2 and a God card behind them

Yugi's box had him up front with Slifer behind him, to the right was Kaiba with Obelisk, and to the left was Joey/Jounuchi with Ra

Kaiba's box had him up front with Obelisk behind him, to the right was Yugi and Slifer, and to the left was Joey/Jounuchi and Ra

Joey's/Jounuchi's box had him up front with Ra behind him, to the right was Kaiba with Obelisk, and to the left was Yugi with Slifer
