Yes, you are right, Stefan. AI build cities only to grassland and plain terrain. So, if you make map what doesn't have these terrains then AI doesn't build any cities regardless how many settlers he has.
If you are making scenario what has settler units but you don't want that AI builds new cities, then it is good idea to use grassland and plain terrains only as special resources for cities (place them near existing cities where AI doesn't build new cities anyway).
