A pithy observation of my own about GNS, since it seems to be a rage of people talking about it, from the 20×20 room entry, through Ginger, and Arref, Doyce, and and of course a long thread over at Rpg.net
GNS reminds me a bit of String Theory.
String Theory is a controversial, dense theoretical branch of particle physics that supposes that at the bottom of everything are multidimensional strings of short length. It’s proponents are sometimes fanatical in their belief that their theory explains all of the mysteries and problems surrounding modern particle physics. And there are a large proportion of people who think its a very pretty edifice that doesn’t describe the real world at all.
Sort of like GNS, don’t you think?
And if you want to read more about String Theory, I highly recommend Brian Greene’s ELEGANT UNIVERSE
