Okay, so here's my idea for either a new CJ, or a new region to add to this CJ.
Crosley is an island in the English channel, located west of Guernsey and Jersey. It is similar to San Pedro in being in a chain of islands, but is different in that Crosley is a British crown dependency, whereas San Pedro is an independent country.
Below is a picture of a suburb near the capital city. Obviously the whole region won't be about small towns and suburbs, but I don't wanna spoil the urban city.
What do you think?
