I don't know about that I'd say we're doing pretty good on the MMO scene. FF XIV really revitalized the space, but WoW is still chugging along, ESO, Star Wars, New World, Guild Wars, EVE, MMO Lite Destiny 2, etc. Basically there are a lot of MMOs with really stable populations where doing activities isn't cumbersome and you can play whatever aesthetic (fantasy, space, etc) you'd like.

It's certainly different from the age of MMO's like Ultima though and the sense of community is vastly different than it was back then by virtue of how mainstream they are now and because of all the different tools and such people use to build those communities now.

So if not golden, I'd say still pretty strong silver.

To your other points though I completely agree.
