Nintendo's latest Balance Board-equipped game is a WiiWare title that combines the rush of rock climbing with the thrill of single guitar chords. Rock and Roll Climber
uses the Wiimote and Nunchuk to simulate arm movements while climbing, while the Balance Board acts to read leg movements. According to our liveblog, at the top of the rock wall, "The character reaches the top, picks up a guitar, and plays a single riff."
This isn't entirely unexpected -- the title showed up on the ESRB database last week, but Nintendo apparently wasn't ready to tell us about it!
