Victory Conditions (Scenario Properties)
Determines which victory conditions are available in this scenario. By default, the all Civ III victory conditions are enabled. If this is unchecked, you may then enable or disable individual victory conditions by CTRL-clicking individual conditions.

Note that any victory condition not enabled in this listbox may not be enabled at the game setup screen. Players may still choose to disable any victory conditions you have enabled, but they cannot enable any conditions that have been disabled.
