So I'm sorry, English is not my cup of tea, I use google trad.
I will throw ideas, you see what you do.
The 1st is like a game of conquest; Base the game on it; Make different kingdoms (perhaps enlarge the map?) And so with regard to sex events, by slavery, rape, torture, prison.
Adding buildings to the capital? So have the ability to build buildings to have other kind of units. See even places of lust in addition?
Different ways to recruit men? (Normal way, forced enlistment, kiss to enlist?) Have different style of men (infantry, archers, riders, generals with different ways to convince them to fight for our cause)
Filters on the map to find out which boxes belong to whom?
Diplomacy worked, being able to be at war / pact of nonaggression / neutral / ally / vassal?
To be able to lose the war, and become a vassal of a kingdom and begin again the conquest of the map?
No game over, but sex events after a battle defeat, ambush etc?
Moral system, Moral raising of men in different ways?
