Intersting distinction. Thank you."In role-playing, participants adopt characters, or parts, that have personalities, motivations, and backgrounds different from their own. Role-playing is like being in an improvisational drama or free-form theatre, in which the participants are the actors who are playing parts."
The character (or part) of leader of the human race is different from who I am. Check.
The personality is mine. No check.
The motivations relate to being a ruler of the world, which I'm not, but I try to make the decisions based on what my real motives might be. Tie.
Background is certainly not mine. Check.
So, only my personality is not role-playing. The rest either is or it's a grey area. Thus, I'm voting that I am role-playing with a preference for carrying my personality in to the game as much as possible. That sounds about right.
