Let's see:

Dominions 3: The Mandate of Heaven - Taken from the Chinese concept, obviously. It's appropriate, since, unlike Divine Right, it can legitimise revolution, struggle and war. An Asian concept is also nice, since Dom 3 will have more nations inspired by Asian cultures.

Dominions 3: Sorcery and Steel - If national units are more useful versus magic, then this title might be suitable. Sorcery technically refers to only half of the Dominions magic schools, but it just sounds cool. 'Steel' could refer to the elemental magics as well, I suppose.
