What I am missing in any game with strategic and tactical accent is the charm of fighting formations. Well, it will be nice if the unit is represented as group of soldiers in formation that can be changed according to you command - line, square, wedge, double line, etc. So on the map screen you have a flagman that represent your army but the real battle is ongoing on the battle field where tactics and smart moves, bravery traits of individuals (heroes) brings the income - Victory!
After the battle we are all generals!
