What the "RP" in "RPG" Stands For

Ah, the never-ending quest for an RPG discussion site.  The Rampant Coyote points out a post by Brian 'Psychochild' Green (Meridian 59) titled What the "RP" in "RPG" Stands For and adds some comments of his own.  I don't think anything gets resolved or proven but he makes some interesting points:

What's interesting is that as games try to define more roles for a character, it becomes more restrictive. Maybe the role I want to play wasn't defined by the developers. Or, maybe what the developers consider "noble" is different than what I do for my character. It can actually be jarring to hear my stoic fighter grunting in pain because the developers wanted to add voice to the game. So, defining more roles doesn't necessarily add to role-playing.
