I remember that part in GEB - I was pretty confused at first, hehe.
I would really like videogames to be more like "states of being" that you can immerse yourself in for five minutes or five hours, depending on how you feel and how much time you have. Like bathing in stories.
I really like this idea too. At the moment, short-session casual games do something like this, without the "story" part. Not sure if that's relevant though. Anyway, I'll think about this.
