The Last Conformist
Irresistibly Attractive
A Cold War scenario without preplaced cities would be ... weird.
Not that that's necessarily a bad thing, but if you want my suggestion, go with preplaced cities and a revealed map.
You could lump all cities that belong to no playable civ to a "passive" civ unable to build anything (uncheck "manage production" in Civilizations menu). If you don't want everybody and their dog's grandma picking at this civ, you could give them hopelessly strong but immobile defenders in their cities.
