Do you role-play in MP games and why or why not?

Always some role playing, especially on the diplomacy side. Tactical and strategic decisions are never affected by the role playing, though. My gods don't hire incompetents so the commanders are left to figure out the conquest on their own. As in, "Thus it was ordered and so it was done!" type of field leadership and the choice of methods whatever was most efficiently at hand.
