new cities can be up to 26 if the startmap is less then 26. if u start with a map which has more than 26 cities u wont be able to eastablish more.
in the long term contest all 40 cities are given and u must grow up and supply them :). u can create your own map in map editor and try out a map with 33 or 35 cities, it's up to you :).
