I’m a member of a Discord server like that. It’s named Past Gen. This is the server’s own introduction:

Welcome to Past Gen Gaming! We’re a community of generally older, but mainly patient and relaxed gamers. There is no age requirement to join us, just the mindset. We won’t tolerate elitism, toxicity, nor any form of hatred. A lot of us don’t have a lot of free time, so when we do, we like it to be a good time. So sit back, relax, and let’s play some games together.

Just let me know if you’d like an invitation link. If so, I would DM it to you instead of posting it publicly.
