How are the conditions of a team victory calculated?
It is clear that when playing a Team game of Civilization 4, teams win or lose together as a team. However, it is not clear how the target goals of these conditions are calculated, and it can be very time-consuming to attempt to determine this. Is a cultural victory triggered when the requisite number of legendary culture cities are achieved between all team members combined, or must they all belong to a single player? Do Civilizations on a team build their own collective Space Ship, or each build one separately? Are players voted for regarding Diplomatic victories collectively or separately? Please be specific - it's possible each type of victory may have a different answer.
