Boston – New York City

I could rephrase that sentence as follows: [b][i]"Striped areas will grant you a bonus only if held together with one or both adjacent regions of the same colors."[/i][/b] Maybe this would sound simpler and clearer.

Changed the title and removed some useless text [spoiler=New Title][img]https://i.ibb.co/HfwyJ8G2/Boston-NYC-44.jpg[/img][/spoiler]

Imo the new writing looks much much better than the previous! I woud play around with the white lines and look how it looks if you replace it with white dots. In this case dots could look a bit better. Maybe the upper title could be a slightly smaller, due to dimensions: you made the boston and NY writings smaller and now maybe this headline must become smaller a bit to remain proportional.

There are still many things to fix, but I wanted to show the new title in first place. Thanks @@Dima for your comment and suggestions. The [i]upper title[/i] is the correct geographic definition of this map, "Boston" and "New York City" are just two territory labels that [u]serve as title[/u] to make it simpler. Yes, perhaps the [i]upper title[/i] a bit smaller may look better. I'm not a huge fan of the dotted lines, I rather like well-visible dashed lines, I'll try to change them anyway. I could have sent you the images Dima, but for now I'm trying to finish it by myself,.. You have already too many maps in developement!
