Several suggestions

Larger cities. I would like to see expansive cities with upper class citizens and people in control <Peaceful npcs to crazy tyrants>

Larger buildable cities. I would like to create a fully functioning town. I have read were you had reasons for making research not need people standing around doing nothing but research. But i want that, I would like scientists that i need to protect. World renowned armor or weapon smiths that i can try to hire to be apart of my town. Amazing architect that build wonders in my town attracting people to me. Farmers to feed my people. All of them though able to pick up a weapon useless in battle gives me a reason to have permanent soldiers.

Slavery. Those same farmers/ architects / Smiths that i could hire i should have the option of capturing them and forcing them to work for me. This could anger a lot of the factions in the game causing them to hunt me down to free these men/women.

Wound flavor text. If my soldier takes a wound taking a vital stat to 0 he should get a wound. a little flavor text describing the wound that goes onto the character sheet somewhere. This same wound could keep that stat from going back to 100%. A nasty abdominal wound that never had the chance to heal correctly making my max stat 75% so if i take any more wounds to that area its a soft spot that drops my soldier faster.

Ability to conquer. I would love to wipe a city off the map and take the town over with full build rights.

Espionage. The game has a day/night cycle. So should the people inside the game. I would like each person inside the game need a place of his own. If i wanted to break into the mayors house in the middle of the night and assassinate him i should be able to. This should also force the town to elect a new mayor. This could turn a peaceful town into a warmongering place or vice versa i could kill a tyrant that has been attacking my cities to slow down their aggression till a new leader is chosen or takes the right of leader for himself.

I think you'll probably get a lot of these as already somewhat planned. Stealth isn't in the game yet but there is a stat for it which im guessing will lead to your espionage. This game is part rts so conquering things will likely be in there.
