Partly because the Galactic Milieu has historically already been rescuing "dead" or "endangered" cryptos, I am a little curious as to whether your data retains enough ownership data to enable at least some kind of attempted continuance in which all the characters for example could be set up with something(s) in lieu of, and maybe even in emulation of, the things they had.

Of the places-and-things representations the Milieu uses possibly Crossfire-RPG could work to set up a representation of characters and places that existed? Or maybe CoffeeMUD might be better?

Maybe a team could organise via this thread to brainstorm on details?

If value can be re-injected into the thing maybe given enough players who owned enough things we can re-inject value into could raise however much you might be looking to sell for, or maybe you could even consider being paid in the very media of the representation(s) of it all that we manage to inject value into?
