[2023] Make your character an offline npc

There was a game I played a long time ago and don't remember the name. But I remember there a was a cool feature where you go in the city ,transform into a medium mushroom and players could buy what ever your selling AND you could log off and your character/mushroom would still be there for a time.

I think It could make the Node alive if players could make their characters offline and become an NPC, selling or even become guards.

Thanks for reading
