Civ IV Tip #2: Check the Cultural Points on the Victory Screen
From your Medieval period on, be sure to check the Victory Conditions screen often, especially for the cultural point leader among your opponents. Number one reason is that the screen will list the opponent most likely to win a cultural victory over you.
Once a Civ gets three cities with Legendary status (50,000 culture points) the game ends.Whether you are going for a cultural victory yourself or not, while planning your own victory, a secondary task would be to prepare for a war against that cultural leading opponent, perhaps centuries down the line. If they look like they’re getting close to a cultural victory, attack.
Secondarily, since there are only three cities that count toward a cultural victoy, you can check this list for your own three leading cities. This would be so that you can concentrate your cultural efforts in those cities alone. Build the cultural wonders there. Don’t even bother building culture-contributing improvements in any other cities for the purpose of contributing culture, unless the improvement gives something the city needs to maintain order, productivity or something that contributes to your entire Civ (knowledge or gold.) For instance, a Theatre contributes culture only to the city where it’s built (and one Great Person point .) You ‘ll not want to use resources or time building them in cities that are not candidates for cultural bringing cultural victory. Except you will have to build enough (five) to qualify for the Globe Theatre national wonder.
