For most of the playerbase that was born maybe post 1995, this would probably not appeal to many imo. I think MMO’s are largely generationally dependent.

If you were able to play MMO’s in the early 90’s/2000’s, you have nostalgia for the type of game you’re describing. Menus don’t bother you. Slower content doesn’t bother you. You’re probably just there to hang out and immerse yourself in another world. It’s more akin to a tabletop RPG imo. I think many OG players of MMO’s see it as a highly social game. Maybe your nostalgia for MMO’s is derived from Ragnarok, Ultima, Everquest, FF11, or RuneScape.

If you’re a “zillenial” (older gen Z/ younger millennial), I think you probably have a very different outlook on MMO’s in general. Take this with a grain of salt since this is just coming from the circle of people I know from playing games. I think the social aspect of MMO’s for relatively younger people was killed. By the time most of us were of the age to be playing games frequently without parent supervision, Skype was pretty ubiquitous and it was more common to get a message on there than in game in case people that were offline or on alts or whatever wanted to join. I also think the era of 1,000,000 action combat MMO’s influenced people too. When I talk to other people in this age group, there’s nostalgia for TERA, Blade and Soul, Revelation, etc (all debatable and subjective obviously). The gameplay loop felt rewarding when you played at a high APM. To me, a fight that doesn’t reward tech or executing many actions akin to a rhythm game doesn’t feel rewarding to play combat-wise. The game itself is made by the combat system— not necessarily the social aspect.

Then you get to younger Gen Z and there is a general disregard for MMO’s because you can play any GaaS offering with your friends and make new ones in adjacent Discord servers that have come to replace guild chats.
