Amplitude (2003 - PS2)
Amplitude is a fun, innovative, challenging, and addictive rhythm-matching game that is a predecessor of sorts to the Rock Band and Guitar Hero series. I beat Amplitude on Mellow and Normal in August, and then on Brutal in September, but haven't finished it on Insane yet. But what's great about it is that finishing it isn't even the only goal that's worth pushing for - you can also play it just to improve your scores or listen to the fantastic soundtrack that includes songs from popular recording artists like David Bowie and Weezer.
