How-To Question: Selecting Civs

[ZargonX]

Could anyone give me a rundown of how to create a mod so that the player has a choice between several civs, with AI civs pre-assigned, so that they always start in the same place?

i.e., The player can choose any civ except Rome, Greece, and Egypt, which are already placed, and the player will start in the same place every time.

I know how to make certain civs selectable and non-selectable, but how do I set the player's civ to a choice?

As far as Im aware....when you are editing the wb map file, in the 'player' mode you switch between the civ leaders and create the original units ie settlers etc and insert them in the spot you desire.

However, Im still trying to find out how you get to assign which nations/leaders you can choose from this list, as my list is only showing certain leaders and not all.
Hope this helps.
