The only revision of the Persistent World forum I would support is the Superhero Sandbox games run by people like [@AndyC], [@Lord Wraith], and [@Nitemare Shape]. They tend to have the population for it among other factors. Might just be me, though. I'm not sure if repurposing it as a multiverse thing would be something that interests me in participating in the subforum and I believe outside of a handful of RPs such RPs are a minority in terms of popularity and activity. I don't know, really.
