Lunar (series)

The Lunar games are a series of role-playing video games, developed by Game Arts in Japan and published in the United States by Working Designs, Ubisoft, and Xseed Games.

The original releases of The Silver Star and Eternal Blue, were published for Mega-CD in Japan and Sega CD in North America. They were later remade for the Japanese Sega Saturn with considerable story, graphical, and musical changes. These remakes were later ported to the PlayStation in Japan and North America. 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 and PlayStation Portable in Japan and North America.

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.
