It seems very cool at the time. First game I remember spending lots of time on was probably Jet Set Willy, in the mid 80s. But yeah, some kids were playing but mostly only those who’s parents had computers. They were expensive and we weren’t well off at all, someone at church lent us one because I got into coding. But you’re right, it was probably around 10%. I would expect that figure to be higher amongst families with more money though probably not much higher.
I was actually the poor kid in a rich area so like my friend had a commodore and the game consoles as they came out (and his family was like average wealth for the area). Money was definitely not stopping most of the kids from being into video games. Arcades were very active to so nothing keeping kids from being into gaming by going to the arcades but again it was a crowd that had almost 100% overlap with the comic book shop.
