Music games aren't just another genre, they're another universe. Inside that category you have everything from hit-the-button-at-exactly-the-right-moment of Space Channel 5 to the ensemble jamming of Rock Band. But once upon a time before music games were all that popular there was a cute funny Japanese title called Parappa the Rapper for the Playstation that redefined what could make a good game. It featured cute animals in a wacky story that required you to push the buttons in time to the music, but also let you freestyle and improvise to a degree to get the highest scores. The songs were strange but extremely catchy, and the characters were so lovable that people who were looking for something different couldn't help but love it.
