In many games with randomly generated terrain, there is no overarching logic to the world. If you want to find a specific area, your best course of action is to travel as far as possible in a straight line, and eventually you'll encounter the terrain you're looking for.

While this system has benefits, we've got a different idea. We want the arctic to be in the north, and the tropics should be in the south. If you're looking for those areas, you'll always know in which general direction you should head.

So during the past weeks, we've been working on a system to generate unique, random worlds which still conform to general, overarching rules. The result can be seen in this video:

We're very happy with how it has turned out! We'd like to allow people to explore all directions, so there is a "New World" in the west and a "Far East" in the east. These other biomes should have unique resources, to encourage players to explore and settle new lands.

It would be a bit weird if you could build two colonies right next to each other, but on opposite sides of the "biome border", allowing you to acquire all the resources of two biomes in one big "double city". That's why all the "useful" biomes are separated from each other by "useless" biomes.

• You need to traverse the tundra before you discover the arctic
  
• You need to cross the steppe before you discover the Far East
  
• You need to survive the desert before you discover the tropics
  
• You need to sail across the ocean before you discover the New World
