This region will not be so easy to fill unless you make cities too fast, it will provide a big playground to make lots of cities. Alot of diversity to any kind of player making various cities. This also has alot of flat land too to build normal cities, it has a nice coast and the Badlands in the Up left corner. It has alot of diverse rivers and few mountain ranges and many islands. It's also a handmade region, with the in-game tools I have made the this.
This is my second upload and this is BananaLand V2.
