The Lunar games, made by Game Arts and published in the United States by Working Designs, and later, Ubisoft and XSeed, are a series of console RPGs. The original releases of The Silver Star and Eternal Blue, for Mega CD/Sega CD, were later remade for the Sega Saturn with considerable story, graphical, and musical changes; these remakes were later ported to the PlayStation. The first game was also ported to the Microsoft Windows computer platform in Japan and Korea, and was later remade for the Game Boy Advance. A side-story game, Lunar: Walking School for the Game Gear, was also remade for the Sega Saturn but has seen no North America release in any form. Backed by publisher Ubisoft, Game Arts created a new Lunar installment for the Nintendo DS, released in September 2005 in North America. The Lunar series is noted for its high level of NPC interaction, well composed music, and excellent characterization of the main protagonists. Much of the flavor of the English language versions of Lunar series games (the sense of humor, bubbly character voices, etc.) is thanks to the colorful translation job done by Working Designs.
