As said, good movies are good movies. Same with any form of entertainment. People still enjoy books that are now centuries old. Good things stand test of time, bad tend to be forgotten and left in dustbox of history.
I heard term "modern sensibilities", but no one can clearly define what those are. FE, my friend and long time DM has new group of newbs. They are all early to mid 20s, he is "old man" ( just turned 30 this year). They play PF1. PF1 is 15 years old game ( and if we are being precise it's 15 year old update on 23 year old game). They are having a blast playing it. It suits their play stlye and his DM style.
On the other hand, i play with other group, we are all mid 30s to early 40s. 5e is our jam mostly for right amount of simplicity and complexity. I run some Mork Borg, Knave and Cairn. They liked it for fast one shots, but they all said it was to bare bones for longer games.
I'll gladly admit, i haven't played tons of games, and most of them i played back in college ( we played decent amount of 7th sea, Houses of the bloodied - by John Wick XD, oWoD, nWoD). My group just doesn't really have time to learn more complex systems. We are happy if we can scrounge up 3-4 hours per session and playing week after week consistently is already a win for us.
If by modern it means easy and logical plus decently fast char creation for starting characters, rulebooks with good layouts where rules are clear and concise and sorted in logical order, system is easy to learn ( not necessarily easy to master, just easy to learn without sharp learning curves), then sure, i'm for it. But i know there are groups who like rules heavy, crunch heavy, complex systems with lots of options to tweak around.
