Activate color and shape coding on the mini map to find locations MUCH easier: Black square for owned cities with black triangle for subject cities, red square for enemy units with red triangle for neutral, blue square for friendly units with blue triangle for allies, green for rhelm areas, square yellow for explored production sites with yellow triangle for unexplored. You get the idea. Second suggestion – Rally flag. Allow the gamer to set a rally flag on both maps and allow an option to each newly created unit to Rally to it. Move the flag and all heading for it will change to the new location.
