only missing point about this game is some of the real word parameters like moral,flanking etc. Maybe a real history mod would be amazing like ancient era or medieval ages.

Modern strategy games for leisure can be traced back to actual militaries or hardcore history buffs—systems that would try to model morale etc., often to a degree which, er, doesn't have mass-market appeal. :p
