Screw Rock Band, the Parappa series was around long before they were pretending video games were more fun than spending 100 hours learning a musical instrument. Which they aren't! Have you ever seen a busker with a Guitar Hero controller? That's because you'd starve to death.
Anyhow, this is by no means an original idea but I thought it would be fun to do. The song is fairly simple to riff on, even for a 'musician' of my limited skill. I did spend an hour messing around with improvisations, though, and created a rhythm section but the resulting mix sounded like a train. :P
No more parts to come, despite allusions to the contrary. A conventional Bog Standard Walkthrough is a distinct possibility, however, since I did buy the game on PSN over the weekend.
