So a big thing about stuff like WoW classic and Everquest 1999 is entirely because there are large sections of the playerbase that want to go back to those early years due to dislike of what the modern game is, add in some were also private servers that got official support. Now we go back to the subject of 1.0. a time where I have seen no one have nostalgia for, something people consistently say was a nightmare of a game because of how much content it lacked, it's disorganized story and generally just wasn't fun.

like there's no real reason to go back to 1.0, it'd gain more traction if we asked for FFXIV classic but it was original launch ARR because of how much of a nightmare 1.0 was. Devs don't just half-heartedly decide to nuke their entire game and change it entirely from the ground up, they did so because what was there just wasn't good.
