To be frank, I knew Hand in Hand for Future Tone is cut for at least 20 seconds when compared to Project DIVA X, but never thought it was shortened even further. For this case, I am sticking with Project DIVA X this time, in terms of both difficulty and playability. Please take note of the music from your speakers/headphones: Left channel: Project DIVA X Right channel: Project DIVA Arcade Future Tone
