Connect 2 cities

[frProlife]

Hi ! I'm New and i have a question : how to connect cities? I have my first complete city built and I want to connect it to another city to have something bigger. when I create a region, I can "select" the size of an area or remove the "borders" to make a single map. Thanks

Of course, I am not a professional, but it seems that it is impossible to combine already created cities

this is impossible you can only connect citys in the create region but the two citys will have the same city name
