Activities at the core of RPGs

Thinking about the discussion at anyway has inspired yet another thought.  I think it would be quite interesting to use this as a starting point for thinking about roleplaying, and see where it leads.  The thought is something like this: the purpose of system in an RPG is to generate validation of contributions (including, but not limited, to moves?) to the fiction, and that validation is perpetually contingent - that is, it can be challenged, retracted, or modified at any time.

That may still need a ton of work, and it may not say anything more than what Boss-Baker already say.  Or - part of that principle is about the realization of what system is: that it is revealed retroactivly by whatever the people involved actually do.  It certainly touches on what system is for (its' purpose), but maybe it would be helpful to split things up into what system IS, where it comes FROM, and what it DOES?

All still less-than-full-formed, but I wanted to get something down in case the holidays overwhelmed me.
