I mean, that's really the goal of the MMORPG genre though isn't it? Having played pretty much all the big ones now, I think FFXIV has the best sense of community though. The last time played WoW it seemed kind of dead community-wise, even the guild I joined. No one talked in it. It sucked.

ESO was good too when I played it, but I haven't played ESO since 2018, so I have no clue how it is now. I'm currently playing GW2 and I have seen very little interaction or guild advertisement, but that may be because I am playing the free version and hBdnt bought any of the expansions yet, so my character is somewhat limited.
