I agree though, I already had significant time on my Atari 2600 and on my father’s Intellivision before NES came out.
For example, I had no problem setting my Atari games down as a child; there's only so many rounds of Pac-Man I could stand even then. Had I been inducted into gaming with Super Mario World and Final Fantasy II instead, well, my parents would have had a much harder time of it.
Wasn't even the first in the category of "first-generation of video game consoles". See https://en.wikipedia.org/wiki/Video_game_console#First_gener... .
I was born in 1973 and had consoles growing up, the Atari 2600 being the second not long after it came out (don't remember what the first was, except that it didn't use cartridges and had a few built-in games.)
People of about my age and even a little earlier were widely recognized at the time as being the first to have a digital childhood.
The idea that there is a “microgeneration” born later characterized by an analog childhood and digital adulthood is silly.
