I am almost sure they discussed this on the last dev stream (or maybe one before). Allowing players to have several different saved games. In essence would allow you to have different “characters” for different game worlds.
It would be like starting several games with different toons. No mention on when they would do it, just that they were thinking about adding it to the game at some stage.
I may be off on this as I am a little ill atm, but I am sure I remember something along those lines.
