So I am behind the curve for VRChat. I never got into it, and only recently tried it because my friend pressured me into it. Naturally the first thing I look up on 'Worlds' is "FFXI". And OMG. Someone created a freaken amazing Chateau d'Oraguille, Ru'Lude Gardens, and Airship!
So if you play VRChat, or have a VRHeadset, you can experience these places in first-person ish.
My only sadness with the Airship is that we can't see Vanadiel from below, but I guess VRChat has limitations.
I was reading online that more Worlds were made too, but they're not by default in the game to access.
