@Jumpin: I like the emphasis on Gameplay in your definition. With a pen&paper RPG you also don't need to show skill as a player, you only state what the character does and success is decided based on what you have written at the character sheet and dices.
@Scoobes: I fully agree on the storyline and AI-aspect you wrote. Also that the freedom of nonlinear games give you at least some illusion, that you control the story.
@neerdowell: This acting out a scripted story with the main character you play is classical called an adventure. In Monkey Island you play Guybrush Threepwood, the story is fixed, you lead the character through this story, so act out the character based on the script of the game. And I agree, that Role Creating Game would be a very fitting name for classic RPGs.
