Recently released in Japan, Hiite Utaeru DS Guitar M-06 is not so much a game, but turns your DS into an acoustic guitar! Curious on how it works? Head over to Youtube to see a short video giving the game a review. The minus side however, there is no saving of any song you might create.
However, Ubisoft has picked up the American license for this game, and will be released in June of '07. The American version will contain a save feature, and will be under the title "Jam Session." This is great news for those musicians out there who might think of a quick tune on the go! Not to mention being able to play the DS at your next gig!
