Honestly, it wasn't really til the end of the 2nd Ed. era and the start of 3rd that, for myself and most of the people I personally played with, the official rules became more than just a basic framework to support "Roll dice and make **** up". During the 1st Ed. days, if there wasn't an actual chart in the book for a particular rule I probably wasn't using that rule, and I routinely ignored weapon speeds, damage vs. armor types, class level limits by race, and at least a couple other things that seemed like they were getting in the way of just having fun playing the game.
I'm 50 years old. I learned to play when I was eight. I used to tell people I played with, "I have dice older than you."
Now I talk to the teenagers playing 5E and tell them, "I have dice older than your parents."
