Dragon Quest I & II is a collection of RPGs developed and published by Enix (now Square Enix), originally released in 1999 for the Game Boy Color. The compilation includes the first two entries of the series: Dragon Quest and Dragon Quest II. Both games use the classic turn-based battle system, casting players as heroes embarking on journeys to save the world. The visuals have been redesigned to suit the Game Boy Color hardware while preserving the original's classic elements. With rich storytelling, deep characters, and a memorable soundtrack by composer Koichi Sugiyama, the games deliver an immersive sense of adventure. This Traditional Chinese revised edition, jointly produced by the unknown and Starnight of Illusion translation teams, aims to provide Chinese-speaking players with a higher-quality experience. Widely beloved worldwide, the collection is regarded as a quintessential entry in the RPG genre.
