The Atelier series is a series of role-playing video games developed by the Gust Corporation since 1997, primarily for the PlayStation consoles (original, PS2, and PS3), though portable versions for the Game Boy Color, Game Boy Advance, Nintendo DS, and PlayStation Portable have also been made. Two of the games in the series were ported to the Sega Saturn and Dreamcast. The series has been primarily released in Japan, though recent titles have been localized for other markets. The game series, based on the definition of 'atelier' as an artist's workshop, is heavily based around the art of alchemy, requiring the player to find and collect items and combine them in recipes to create better items with which to progress further in the game. A manga adaptation by Yoshihiko Ochi has also been published.
