Unlike the more action-focused Hunter x Hunter: Ryumyaku no Saidan (PS1), Maboroshi no Greed Island is an original story where players create a custom protagonist who enters Greed Island—a dangerous, card-based real-life RPG. The player teams up with Gon, Killua, Kurapika, Leorio, Hisoka, and others to clear events not depicted in the manga or anime. The game features turn-based combat, card collection, spell systems, and multiple endings, making translation essential for understanding objectives, card effects, and story branches.
