>It probably can't be scaled up. 

There's one place it can scale, if you do it top down- mmorpgs. If all the players are lead by the same hero king lord british whoever the fuck, that's a role where it could be both practical and affordable to make playing the character someone's job. You're not gonna pay an actor to be a quest giver who stands around and hands out the same boar killing quest to every player over and over, but royal proclamations and the other "stage" and story events sure it can work live down to a certain level. 

I think that might even help make a game feel less like a ride everyone is taking a turn on and more like a shared world. [spoiler]And look how people love both vtubers and the main characters in normal mmos, of course a game could exploit both[/spoiler]
