It was, but video games weren't as mainstream compared to now. Of course, you have the rapid expansion of the Internet to think for that. Around 2009, Call of Duty was THE video game to talk about.
Well, I guess that also depends on what it's mainstream for. Little boys and male teenagers, they all played games. I hear old-timers here talk about people getting bullied for playing games, and I think, what, in the Stone Age? Back on your Amiga Commodore COLOSSUS whatever? The idea sounds so far fetched, I don't doubt it but it's hard for me to imagine.
Girls, on the other hand, did not game. I think there were two things that changed. One was gaming was pitched to them through shitty phone games. And I can remember back to when Internet losers would get really pissed at "casual gaming" and Candy Crush and stuff, for no reason other than spite that other people like different things. That might have been a slow but sure gateway. Women played the phone games, men, not near as much. This was all when smartphones took off, I remember when those were still businessmen's luxuries. Then, I think a lot of the girls got lured in by the men. At the first it was fat chicks, smelly nerds, people like that, but epic gaming got to be so common women had to decide they liked it so they could chase the Chads around. Just like the many women who don't have a genuine interest in male spectator sports, but women tend to adopt (at least in a superficial way) male interests for attention/to bond.
I don't think, remembering back to it, that older adults played games, and younger ones didn't take them real seriously. They were still taboo in a way like toys are for adults. (Or were, who knows with adults watching bullshit like Bluey now.)
