I love me old video games to bits but:
One thing I'll add to that is that I speak about old games in general rather than just the ones I grew up with. I can play a PSX game I never heard of before because I'm used to the usual curveballs and technical limitations of the time. Can I reasonably expect someone who grew up with modern gaming to fall in love with tank controls or early 3D graphics that aged like milk? Probably not. Of course, as mentioned by the fine folks earlier, there are exceptions but they are exactly that, exceptions.
Oh, true, games of PS1 and PC of 98-XP generations are "cozy" to me, like I noticed people get stressed with UI of original Fallout or Baldur's Gate, or even Command & Conquer, but to me it's something that's very clear, and it's modern games that feel overwhelming... but give me a DOS era game and I'll also feel off-put by bad UI and I can't make out what I need to press. Then also the games I listed HAD streamlined tutorial areas and explained to you mechanics in dialogues. It isn't as new of a trend as people think, anyone remember Candlekeep? Or FO2 Chamber of Trials?
I also had a Famiclone growing up so to me, NES games are much easier to control than Mega Drive or SNES ones, it doesn't mean they're more accessible, I just didn't have 16-bit consoles for long, quickly jumping from 8 bits into PlayStation and PC. But tons of people, especially Americans, grew up with Nintendos, and they are used to Zelda and Mario physics instead of following Contra with Crash Bandicoot.
Turns out, people find things they grew up with easier, big shocker! I can do Tekken mist steps in my sleep, and DoA throw combos with Izuna Drop, but some Street Fighter motions like Tiger Knee and the amount of mechanics and power bars just make me go BSOD... also, seeing N64 controller layout makes me have an existential crisis, but same person who actually learned to aim in GoldenEye might be bad at playing RTS games with entire keyboard being hotkeys.
Guys, just stop being elitist by pretending the exact thing you grew up with is the hardcore tr00 kvlt no-hand-holding experience, but the things other people play are casual filth! It's pointlessly elitist and gatekeepy. I've read too many comments claiming that Tomb Raider LAU trilogy was the real thing, but I disliked it for being casualized to no end, but even growing up with tank control originals, I enjoyed modern reboots more that the weird era middle child, but good luck explaining that to prequels generation.
Yes, old games often had worse design and were less hand-holdy than, say, Dark Souls. A modern game famous for extremely linear hand-holding tutorial with popups every 2 steps... what, it isn't the typical example of modern game convenience? But it is.
