That's rather tempting. I don't really play any music games outside of Frequency and Amplitude, though I do want to try one of the Dance Dance Revolution games at some point (looks like fun). I don't really have much room to set up a dance pad, which is why I've never invested in home DDR. I've got an EyeToy, though, so maybe this would be worth getting at this price.
Has anyone here played EyeToy: Groove? If so, what do you think of it?
