Well, first you insisted that the "role" in role-playing was a character class.
Then you said it was the character, as if in a story.
Then you argued for the character class again.
Then, when I called you on it, you referred back to your post about it referring to the character in the story.
Now, when pressed, you insist that that's not what you meant.
Incorrect. I first suggested that the "role" referred to a functional role...then I realized it was more about being a character in a story. I have not changed my position on the latter. What has happened is that we have gotten on a tangent about importance of personality versus class in Dungeons & Dragons. Personalites are not required...classes are. That is wholly separate from why it is called a roleplaying game, or how other roleplaying games work.
The "role" in "role-playing" is the character, the persona you take on in the game.
Emphasis added.
I disagree. It has nothing to do with the "persona" but with the fact you play a "character." Your game piece is a character and that is why it's called roleplaying. If your game piece was a tank, it would not be called roleplaying because tank's aren't considered "characters." Battletech is not considered RPG even though there is a person (the pilot) inside your Mech. You can spin a whole story around your Mech and your pilot's piloting and combat skills can increase, but it's still not called an RPG. You can play your Mech with a blood lust or as cold and calculationg tactician, but it's still not an RPG. Battletech wasn't ever thought of as an an "RPG" until it included Mechwarrior. In Mechwarrior you play a "character" not a Mech.
Look, the differnce between our positions is subtle. I'm certain there are RPG's which focus on the "acting" aspect of roleplaying. And in some ways, it might even be a chicken vs the egg discussion. But you can have acting and personalities in how you play armored unit wargames and it still doesn't make them RPG's and you can play D&D devoid of personalty and acting and it is still a roleplaying game. What's true is that because you do have a "character" the game lends itself to the personality focus in a way other games don't.
I can accept an unwillingness on your part in separating the character from the idea you are playing a persona. By definition all characters have personalities...it's just that 1e D&D didn't actually require that you adopt a personality, nor was the game dependent on your persona like it was dependent on your functional role. Again, not related to why it's called roleplaying.
