This... is dumb. Reddit gets traffic from people using it as a secondary search engine to get relevant answers.
Most people on the Internet view it from mobile. Reddit already makes their mobile experience genuinely awful despite this. Blocking it entirely?
The herding to their mobile app is so transparent (and DEFINITELY through stick, not carrot) I'm morbidly curious to see what horrible things they planning to put in their app that they know users will loathe, that requires their alternatives to be zero.
Be 80 and play FIFA, it's fine. There's no age where you are obliged to put down your controller for the last time. But it shouldn't be your first answer while you're dating, and definitely not your only one.
Being a gamer, as an identity, has a lot of baggage.
Having gaming be your only interest or hobby is associated with being an unambitious self-interested person who intends to do as a little as possible, as long as possible. The recognisable games are marketed towards kids/teens with time to burn.
Imagine your date's interest was "moderating Reddit", "watching TikTok", or "reading Instagram". That's what 'gaming' sounds like: your hobby is media consumption.
There's no age where you aren't allowed to consume media; but it's worrying if that consumption is your identity, if consumption makes up your routine.
So it's not actually about age - it's about maturity and goal-setting.
When we're younger, most of us live moment-by-moment. Media consumption offers no future, but it has a pleasurable present.
But as people age, people develop goals and interests that require more investment and focus, and they're looking for people that are doing the same. A cutthroat economy demands people develop goals for financial stability, even if they still otherwise like games.
As we age, we stop looking for somebody to hang out with, but to build a life with.
So once the people you're talking to have interests for the future, "I enjoy my present doing my own thing" doesn't offer them anything. If they don't play games, they don't even know what games are capable of. Maybe one day they'd enjoy playing Ultimate Chicken Horse with you.
But right now, they just see the recognisable titles that want to monopolise children's time, and assume you're doing that. They picture you spending 20+ hours a week playing Fortnite. And there is an age cut-off where it's no longer socially-acceptable to be a child.
It's not that video games are bad, but they're a non-answer. They want to know what you do that's good, and a non-answer implies you don't have a good answer at all, and that makes video games 'bad'.
