ok, thought i would restate it since no one made a comment the first time i posted the idea.
to the best of my knowledge civ4 truncates decimals. i see this as important because the idea of setting it to +1 happy per 4 or 5 units to me seems like a great idea. we can apply this to 4 or 5 of the more militaristic and nationalistic civics as well as even to possible buildings. this would prevent the +1 happy per military unit from being over powered and still allow for unit happiness in the game.
