With this one turning off, which becomes the longest running MMO?

And now is remembered as one of the best of the genre. One can only hope for such a thing to happen again with Cyberpunk 2077. :D

On top of a lot of suggestions already here, I really dug Altered Carbon Season 1. Season 2 is good, but Season 1 really slammed it out of the park for me.

This concept of multiple instances of a platform doesn’t exist outside of the fediverse.

This is not 100% true.

A good comparison might be World of Warcraft. While not the best example, a player does not have to be in the same instance/server as their friend in order to join in each other’s content/dungeons. This is a fairly new feature of WoW ( and not feature-complete compared to full federation ). It could stand in as a starting point for the conversation.
