A few years back, I built a Nintendo because my old one was no longer working. As long as people are connected to their old technology, there will always be a drive to preserve them.
I do believe that gamers growing up with modern systems wont be able to understand what made those older systems magical to us, though. That feeling of disconnection, and being fully engrossed into a game, no matter how ridiculous or difficult it was, simply because it was just you and the game.
