Some would call that roleplayIt certainly doesn't seem like very engaging play. It is less like a game and more like play-acting.

So I suppose it depends on if you find roleplay (or at least this kind of roleplay) engaging or if it's just the game you find engaging.
That was why I called it 'color' and not salient to the play of the game. Again, I think it is fine RP and not to be disparaged on that basis. I would like to point out that something like Burning Wheel wouldn't inhibit this type of play either. Launcelot could have a "Lusts after the Queen" belief, that could be established at the start of play by the player.
If the game is about roleplaying then roleplaying is salient to the game. You have an odd notion that the game is only about whatever the mechanics dictate.
