That's most how most of my life has been in a nutshell; it isn't limited to games. Schools,college, old coworkers. A lot of the glue comes undone the moment you need to move on. I'm a late Millenial, but the advent of social media among Gen Z gave us the ability to connect more intimately than ever over the most niche topics. But at the cost of losing the deep bonds you'd normally form then bundled with a community based on proximity.

I've had long conversations with some former guild mates yet can't point you to a name or face. I know quite a few never even lived in my country. But things loosen up once the game shuts down or one of us needs to move on. It's neat in some ways, hollow in others.

On the larger scale, it's why local community is also weaker than ever. No one really puts and effort to come down to community events, or they may come once or twice and never again. Those gatherings are also less frequent than ever, often once a month. You can't really form a deep bond meeting once a month. So meetups end up frustrating in their own way (at least, the tech meetup. Maybe a run club would be different).

I've even heard notions that it's easier to find a mate than a close friend these days. I can completely believe it.

I'm also in my 30s so I get it. The only real advice I can give is that it just takes more work to maintain friends as we get older. I had to be the one reaching out rather than waiting for others to reach out to me.

The other thing is recognize where friendships came from. Most of it was just being physically near people. Sitting in the same classrooms day to day. If work doesn't create that space (or isn't good enough or you want to distance from work) you need something else that does the same thing. Join a club. Set up weekly beers with your friends. Or literally anything that puts you in the same physical space with the same people, routinely. A friend of mine gets together with his gamer friends once a year and they socialize off the game too.

The convenience of social media is also its weakness. The ease of connecting makes it just as easy to disconnect.

Real friendships require work. That's true of any relationship. I'll tell you my friends can be annoying and exhausting, but I love them and I'll gladly put up with their shit to keep them around. After all, who else is going to put up with my bullshit? lol
