The newly-revealed Wii game comes from the developers of Chibi Robo and will include obscure Nintendo characters such as Birdo and that old guy from Golf on the NES. http://www.nintendoworldreport.com/newsArt.cfm?artid=16323 As E3 rapidly approaches, so do game announcements. While there has not been an official announcement, the Japanese Everybody's Nintendo Channel has unveiled Nintendo's newest intellectual property, Captain Rainbow.
Coming from Skip, the developers of Chibi Robo, Captain Rainbow appears to be the story of Nick, a run-of-the-mill geek who also happens to be a superhero and TV star. However, the colorful captain has fallen on hard times as his TV show is failing and he is falling out of the limelight. In an effort to revive his show, he journeys to Mimin Island where wishes are said to come true. Upon arrival, he finds out that he must make other characters' wishes come true in order to realize his own.
The other characters appear to be a plethora of obscure Nintendo personalities. So far the only three known characters are Birdo of Super Mario Bros. 2 fame, the old guy from Golf for NES, and Hikari from the Japan-only game Shin Onigashima.
The game appears to be a free-roaming action adventure game that shares a similar graphical style to Skip's other games, primarily the Japan-only title GiFTPiA. You will be able to switch between Nick and his vibrant alter-ego to beat enemies up and make people's wishes come true.
More information about Captain Rainbow is anticipated over the ensuing weeks as E3 is right around the corner.
