Volcano Crown
Volcano Crown is a wonderful map to build your city in! Lots of hills surrounding an asleep tropical volcano which turned into a giant lake with rivers streaming down to the sea.
There are several islands you can reach, all transport connections, all resources available.
Oil is hidden on the bottom of the minor lake, you will have to stop the river to dry it and build your industries in.
Enjoy and, if you want, feel free to suggest anything! Will keep this updated
