Captain★Rainbow (キャプテン★レインボー Kyaputen Reinbō) is a video game developed by Skip Ltd. and published by Nintendo for the Wii. The game was released exclusively in Japan on August 28, 2008.
The game puts players in the role of Nick, an ordinary guy whose alter ego “Captain★Rainbow”, was once a popular TV superhero. In order to regain his popularity, Nick travels to Mimin Island, a place where dreams are said to come true. Captain★Rainbow is an action-adventure game that involves making friends with the other island residents (who are all past Nintendo characters), collecting “Kirarin” crystals, and granting their wishes.
You know, the Wii is currently in it’s twilight years. No one is publishing any good games for it, so why not port this over? If Xenoblade can be brought over, so can this.
