Nope, im not using the unofficial patch.
The civs arent really different. The choice of leaders and leader traits are pretty huge, but theres only the unique building/unit and the 2 starting techs. The starting techs dont make much of a difference unless you start in a spot that is very good for a certain tech which you dont start with, but that spretty rare. Other than that though, Russia and say America at anything below gunpowder is exactly the same, combat wise. All their units are the same. And anything after your civ's unique unit age is exactly the same as a generic civ(well, barring leader and unique building).
