I've been seeing this for years. People all over seem to say things like Atari-era games and consoles are "objectively bad" or worthless and that Nintendo invented good games or other garbage. I often hear that you have to be at least 50 years old today to even like "pre-NES" games which is bogus because I'm 27 and have loved that stuff for over a decade. It's frustrating because the time before the NES was such a vibrant, fascinating era that was chock full of variety and interesting stories. The games are still fun today, I love golden era arcade style game design. It's sad that that whole part of gaming history is being slowly erased by Nintendo kids.
I don't really like Top Hat Gaming Man, but he has a point that the average joe would rather watch 2,000 videos about the same Nintendo games he's been playing his whole life than learn about something new. I guess I'm lucky that I'm not an idiot like that and I appreciate the hobby.
I can understand simply not being interested in "pre-NES" gaming, but to actively hate and discredit it or just being angry that it exists is bizarre.
