It's a long path to go down. Retro gaming is a boutique cottage industry. It's not at all like audio because it isn't snake oil. People perceive differences in CRTs, sound chips, analog video and audio drivers, etc. Does any of it matter? Does anything matter?

I like to tinker and I'm a display junkie. Playing retro games revitalizes me by bringing my headspace back to when I was young. Little me loves these toys. It would be trivial for me to fall down a cynical nihilistic cliff any moment of any day. If a utilitarian wants an explanation, they can have that one.
