PaRappa the Rapper review at PALGN.

"The original PaRappa the Rapper hit the gaming scene at just the right time. As gaming moved to larger formats (CDs), this opened up the potential for creating much more immersing gaming experiences around the use of sound and music. As such, the music genre started feeling its way into the gaming world. PaRappa the Rapper was really one of the first in a long line of games to really connect the musical reactions from what was happening on the screen to the inputs that you were giving off the gaming pad. And so, a whole new genre that appealed to a new audience was born as the PS1 took off to being the dominant console of that generation."
