I would say it’s not really an age thing. I mean age probably plays a role but ultimately it’s just a hobby that is relatively common and not very exciting to an outsider.
This is definitely experienced by 20 year olds too. There is definitely a social pressure.
Based on this, 12% of people in your age bracket play video games, it’s typically a roughly 50/50 split by gender. Not exactly a small amount. I think it’s more that if you date 10 women, one will be a gamer and you’ve just not met that one.
