I highly recommend this map script, I am using this and discovered the most unique land masses, more rivers, lakes, coves, etc really makes a huge difference. Ice is nearly gone on edges allowing you to fully circumnavigate the world in most cases as he says.
I used this together with the Larger Worlds by the same author and generated 10 or so Small Continents maps of the largest size and was pretty impressed with the result. Distinct continents with ocean inbetween and occasional large oceans, sometimes a few sometimes lots of islands of various sizes. This was my favorite result:
I like the map that created. I choose fractal and i got a big continent we a few big islands, like more than 8 tiles. The only issue i see, and perhaps is related to the latest patch is that i got zero sea resources.
