My take is that there are a few excellent games from every era... games that will always be worth playing, because their depth transcends whatever technical limitations existed at the time of their completion. Once I was able to break myself out of the hype machine that builds up around each new release, I was able to find more enjoyment in the vast library of games from all times throughout this relatively young technological art form. What is considered "retro" is an ever-advancing classification; perhaps it's more accurate simply to refer to games by the part of the decade in which they were made (late 70s, mid-90s, etc). It seems most people do tend to keep the games of their childhood/teenage years among their favorites of all times, no matter what... but for those open-minded enough to explore further into the past, and onward into the future, a lifetime of enjoyment and appreciation awaits. (The same can be said for true music lovers, who can find delight in the earliest recordings, and, prior to those, sheet music from centuries ago -- just as they can be fascinated with the spectrum of latest releases from indies and huge labels.) Yes, there is a lot of drek to sort through to get to the best stuff. But each era of gaming was forged by artists and technicians doing their best to bring forth their vision, and laying the foundation for those who would follow. I would personally be thrilled to play Space War or Tennis for Two, or the Magnavox Odyssey. I've played some 1970s coin-ops which weren't even video games, more like mechanical games that clearly had an influence on the video games that followed.
This blowhard in the video is just using a pissy attitude to gain some dismal little measure of internet fame. I hardly even like to read random peoples' comments on articles on the internet because it's a mostly festering breeding ground of stupidly rigid opinions.
