I'm starting to think that nostalgia isn't a delusion but a form of false consciousness. Nostalgic people can point out that certain things were better in the past but they cannot figure out why. Take "Games were better back then" for example. It's clear that people say this because of modern AAA gaming but they just don't understand that the worsening of quality of AAA games is due to the gaming business becoming mainstream and "too big to fail" rather than some innate special qualities to these older games that cannot be replicated today. And when it comes to certain games that people remember fondly, it's often not because it's their childhood but rather that these are genuinely good games or at least games that had potential. Therefore using the word "nostalgia" muddies the waters, it's a term that obfuscates discourse and makes people attached to superficial brands and appearances devoid of the content they represented. Nintendo's games were and are good because their developers are talented and pixel art is charming because it looks pretty and stylish, simple as. There was no pixel art in the 80s anyway, your shitty CRT screen turned everything into a blended goop.
In conclusion, we should stop using such a word as "nostalgia" and just say that the AAA games were just simply superior back then because capitalism, deal with it, zoom-zooms. And Sonic was always good… kinda… not really.
