Koei today announced that Opoona, the RPG developed by ArtePiazza for Wii, has been approved for manufacturing and is scheduled to ship to North American retailers on March 25, 2008. Opoona tells the story of a boy who is a descendant of brave warriors, known as Cosmo Guards. During a trip to the planet Landroll, Opoona becomes separated from his family, with his brother and sister missing and his parents injured. In order to find the truth behind these events, Opoona must get a job and a license to travel between colonies.
