Just a reminder: Civ3 was designed to use 8 Civs, MAX.
That is why the screen was designed the way it was. When it was decided at the last minute (development-wise) to increase the number of Civs allowed, it was too late, and would cost too much money, to redesign the screen, so they came up with the 'Shift-Right-Click' thing to provide *some* useful information.
