And your question presumably is, how do you do this?I want to have only one specified civilisation (Player 1) available when you start a new game. I also need the other 30 civilisations to be available to the AI.
If you're using the Firaxis Editor, you assign the 'Playable Civilizations' via the 'Scenario' drop-down menu, option 'Scenario properties'. Just click your 'Player 1' Civ in the list, which should instantly de-highlight all the others, meaning that only the AI can use them.
If you're rather using one of the custom Editors (e.g. @Quintillus') I would assume there is an equivalent function in there as well...?
