Rob Conley has some interesting ideas about a kind of Living OD&D that might be something TARGA might eventually run. (Is that enough "might"s? It's very exploratory in nature, or so it would seem to me.)
What I find fascinating about this is that in matches what people did oh-so-long-ago, where characters and campaigns were not necessarily tied to one another so tightly. Jeff Rients talked about this awhile ago, and his discussion is still spot on. What's a little disheartening is how quickly people want to add some sort of tracking mechanism, when one of the beauties of the OSR is that it recognizes the primacy of the referee in their own game. Even so, it's an interesting discussion.
