Thanks for input
I understand the ideia of rail asia, but i prefer the Northwest Passage(its a CC map) style because the connection stations belongs to both lines, but i can test it both ways to see what looks better to the eye.
I also believe that the most part of rail maps in CC are only suitable and enjoyable for players who play with BOB, and a lot of people dont even know what it is. If u dont use BOB, its just a mess to the eye, and u spend hours finding the right connection.
Here you have 4 distinct lines/colours(in rail asia u have colours too, but they are almost all from the same colour group, so it adds confusion)
About the city regions and and holding stations inside that region for bonus, i like that ideia.
Actually thats not the map you posted, its only the bottom right region called Lisboa.But the idea is just that.
What i think it makes it unique is that there are no Metro maps in more than 100 maps. Toogether with that, your idea of having bonus for stations within a region, makes it original, at least less common.
Apart from that and loving my city , Lisbon does not have any map in CC.
