I am a new player of Civ 4 and I like this game but one thing bother me. When there are more units on the map, mine and other nations, its quite difficult to recognize which are mine, are which belong to the enemy. My question is: is there any mode or graphical improvement that could help me? Im not interested in nice and spectacular appearance; Im looking for lucidity and efficiency. For example, only a quoter with a simple sign instead of picture would be the best for me
