The Cooling of something - like video games - is not as simple as saying 'retro is cool'. That's facile. It's about the inversion of control, and the curious blandness and meaninglessness that hypercompetition creates in products and services. Smart marketers exploit it. Oh wait - smart marketers aren't trying to 'market' in the first place.
But I listen to chip tunes occasionally, so you may want to hyperbolically discount the future value of my statements.
