An MMO i played from 1999-2007 shut down in I think 2017. I still remember the landscapes and landmarks and it is really strange knowing the shared experiences in those places are just flat gone. Inscribed items with messages to other players: deleted.
I have emulated the game world but only fragments were saved by collective efforts in the community before shutdown. Regardless there's simply no people or things to interact with so it feels even more soullessly dead and empty.
