Interesting and global defense on the influence of Game Music on the authors life.
Different chips texture the music differently, and you can tell which console produced a given song from the instrumentation alone. So the same melodies written for different consoles have a distinct musical signature that gives both modern and classic chiptunes a compositional richness you might not expect. Even large scale developers have started appreciating chiptune composition again, and the recent oldschool gaming revival has given us new (if atavistic) games like Mega Man 9, complete with chiptune soundtracks.
