I read the article, and I believe it is being misinterpreted. I think Ryan is talking about GT games, but that can go for any sport-like game with their sequel improving upon them. RPG games, adventure games, platformers, puzzle games etc, these games are worth going back to, as each hold a different experience/story. A new football game/hockey game/Forza game/GT game etc, these would seem to get way less attention from people when it comes to retro gaming (with very few exceptions). That would probably be why these games cost mere pennies in shops nowadays.
So while I think this article is being read into the wrong way, I do believe there is a market for BC/retro gaming. The right kind of games need the support, though. Not just the easiest ones to emulate (which would most likely be the ones no one wants to replay).
