Game Rules (Scenario Properties)
Determines which game options are enabled in this scenario. By default, the all Civ III default game rules are enabled. If this is unchecked, you may then enable or disable individual game rules by CTRL-clicking individual rules.
Note that any rule not enabled in this listbox may not be enabled at the game setup screen. Players may still choose to disable any rules you have enabled, but they cannot enable any rules that have been disabled. Below is a list of game rules and what effects they have.
