The author of the blog post uses a video game to store some of his personal memories:
You knew this from the beginning but my keep is no physical palace. It’s a Memory Palace, a mental construct used before computers or even printing. Mine is based on the first floor of Lord British’s castle from Ultima Underworld II: Labyrinth of Worlds, a game that was the peak of the Western RPG before Morrowind. In UUII, you play the Avatar, a hero trapped in a castle whilst an enemy invades his world, and who must explore the maze of the basements to find the way out. Consider this, then, a retrospective about the sadly-defunct Ultima series, a discussion of an archaic psychological technique used by mystics since the dawn of time but curiously in abeyance during the modern era, and a pyx about the potential for the things we call games to become more than the structural limitations of engine design.
One of the most interesting items for me is in the comments: using a level editor to create memory journeys. Has anyone tried creating custom memory journeys using a video game level editor?
Wikipedia has a list of level editors.
I’ve never played UUII, but I did play Ultima IV many years ago. It was very primitive by today’s standards but highly enjoyable back then.
I’m still on the road at the moment, but will be posting regularly again once I get back to California.
