So Memory Palaces
I've done this before a few times therapeutically, where I make a memory palace as a mental map to analyze some things I was trying to work out. I also started stuffing story and future project ideas into the rooms there, and then I'd enjoy going back and having different characters walk through my memory palace and comment on what they found there.
I'm wondering if there's a solo story game here, or a good procedure, for maintaining a memory palace. Not just for memorizing things, but for keeping ideas and revisiting them.
Has anyone else poked at this?
