For millions of gamers who grew up in the early 2000s, the Yu-Gi-Oh! Power of Chaos trilogy represents the golden age of digital card games. Before the rise of Master Duel or Duel Links, there was Yugi the Destiny, Kaiba the Revenge, and Joey the Passion.

While each game serves as a standalone experience with its own card pool, they were designed as an expanding ecosystem. To access the complete library of over 770 cards in the final installment, Joey the Passion, many players turn to "all cards" unlockers or registry mods. Overview of the Trilogy
