PC gaming took off in the 90s. I'm not clear on the history of consoles but I'm wondering if they became widespread in the 80s? Having these devices at home probably created a larger generation of gamers.
Gaming was "for boys" until very recently, and tbh the inclusion of women as the default audience for games is still a work in progress. Game protagonists are usually male, romance options usually assume the player is a straight man, even the quests and the way NPCs are written are colored by these assumptions.
Video games have gotten so much more complex in a very short amount of time. The storylines are richer, the writing and visual effects have gotten signifixlcantly better. Someone who has only experienced early arcade games or clicker mobile games wouldn't see gaming in general as a worthy hobby for adults.
