discord is an option, probably, though it's a russian roulette to me: never know if you meet a creep in disguise or minor

man i haven't heard of this game in years, honestly
honestly, it seems making friends irl, moreover a partner became way harder, when you're a highschool student or uni student you get among the different people you can engage with, in adulthood you probably have the circle of colleagues at work, but i assume it's not the same as circle of people with similar interests, if you're lucky enough you can befriend someone, but it's just my assumption
