Now that I'm back and have more time...I'll try to catch up on things.
---I'd have to agree that adding the mentioned connection would help out that continent quite a bit, and keep movement much easier.
---As for other gameplay mechanics... I'd look into the bonuses.
- Lantau = fine
- New Territories = could be knocked to a 4 due to only 3 entrances, but still can make an argument for 5 due to the many countries that make up the continent
- Kowloon = also seems be fine, could be maybe a 5.
- Plover Cove = seems off. Consider it has 4 borders and 7 countries, but only a bonus of 4. While Kowloon has 4 borders and 8 countries, but is worth 2 more armies.
- Hong Kong = 3 borders and 6 countries, but a value of 3? Maybe a 4 would be better. Something to consider
- Sai Kung = 3 borders, 8 countries. 4 seems alright, could make an argument for 5, but I think for 4 might be better suited.
As for the visuals...
---I suggest looking into playing with the color tones of the continents. I like that they are bright. It's something that hasn't been experimented with very often here. But the white lettering on the current orange is a little harsh for my eyes.
---Also, I'd look into perhaps making the border's a slightly gray color, similar to what is going on in the green continent. Just so there isn't so much white in the central area.
---If possible, look into making the connection point between Dabu and Sha Tin a little more prominment. Perhaps be erasing a little land.
---As for the ocean, I like it the way it is. But it seems others do not. Maybe post a few images of varying degrees or ideas you have. Then you can see where people's interests lie.
---Also, maybe look into fiddling with China's colors a little, and making it not seem so flat.
---And you've done a pretty good job of centralizing the coordinates, A few seem off still. Make sure you go through and recenter those that are a slightly off.
I hope to see a new version coming soon!
