Yes! If we have something other than a passionate character untenable situation etc, it's not Story Now; that's one way. If we don't all do it together and live at the table, now, it's not Story Now; that's the other way. If we approach it with an end state, not just in mind, but decided, then we aren't all doing it collaboratively at the table. Somebody already did it, and now we're intent upon making it so, not upon making our own thing. Consequently, it's not Story Now.
Now this is important! We don't have enough information to decide whether it's Step On Up or Right To Dream instead, or zilchplay. All we can conclude so far is that it's not Story Now. I'm inclined to leave it that way, at least for now.
So to draw this back to the point of the thread: if we have a passionate character in an untenable situation, escalating through crisis after crisis to resolution, and we're all doing it now and live together at the table, it's Story Now. Having exciting scenes that explore character and situation is just part of roleplaying, and could be contributing to any creative agenda. The fact that Apocalypse World's rules help you create exciting scenes that explore character and situation doesn't mean that it's not a Story Now game; the fact that Apocalypse World's rules help you create passionate characters, untenable situations, escalation, crisis and resolution, live at the table, DOES mean that it's a Story Now game.
Nocker, Michael, make sense?
