I've been spending some time on my world-crafting shenanigans lately, and created one with Masterwork settings that I just had to share.
External picture link, because the image is freaking huge (Legends export)
Features- two large oceans, 1 good & 1 evil, for all manner of beach time !FUN! Also it was necessary in order to create the rivers and waterfalls.
- natural waterfalls (although I was successfully able to create & adjust more using the brush-painting feature of Perfect World).
- A single large mountain formation, plus several smaller ones, allowing the Dwarves a buffer to establish themselves in the world. Occasionally Dwarves are extinct, but that is a rare occurrence.
- Highly mixed and diverse biomes. You can easily get 3+ biomes in your embark if you really want, although the resulting site tends to resemble a magical sneeze
- Vanilla races can usually hold their own, despite the insane number of Beasts and hostile races/invaders (assuming you have them enabled).
- Edit: The North 1/5 of the world is frozen, covering mountain, ocean, and all manner of biomes. Just in case you want to see what a tiger-popsicle looks like.
Just copy the following into your World Gen text file, and create a new world. Enjoy!
