Thanks for your interest. In order to solve that problem, one would have to rise sea level, and therefore, all land that is supposed to be above sea level. I didn't find a fast and easy way to do that when I first made the map. I experimented with some different grayscale settings, but to no avail. However, feel free to edit the map according to your preferences.

lol

Interesting idea, but unfortunately, I don't play Cities Skylines anymore cos there are too many other very good games that I have to play these days. ;-/

Could you make a 81-tiles map from Singapore/Bangkok in the south-west to north Japan and Korea in the north-east please ?

Well, my general advice would be to upgrade to 2x 8 or even 2x 16 GB RAM with high GHz values and run it in dual channel mode for faster loading. ;o)

i have 8gig ram and it takes forever to load, any recommendation?
