One interesting, tangential observation I have drawn from it is the number of players who have said—and many of these are long-time players and refs mind you—that their actual playing experience with this kind of play at the tabletop is minimal to non-existent. Much more of it seems to have been with computer games if anything.
Which makes me curious about the why. How many readers out there have had experiences with this level of play in a tabletop rpg? What was it like? What worked for you? What didn't?
And if you haven't, what was holding you back?
