I would like to see a game where the focus is on people and politics first, and war and territory second. For an idea of what I mean, the main game screen would show who holds positions of power in the royal court, rather than a map. You might start as a minor noble in 1419; the goal would be to gain money, power and honour for your direct mail line, through marriages, making the right friends, and pleasing (or becoming) the king. Of course fighting wars would play a part, but the goal would be to put the right people on the right thrones.
