Here's map based on a picture posted by Nanocyberorgasm.

It's a clean map, no rivers, no ressources. But I think Nano will complete it.

It looks a few stretched on the minimap, but it's due to tiles size and proportion are correct.

Thanks a bunch for the map. Obviously, I lack the image editor required to perform the feats necessary. :)

I do it with PSP8 but there are lots of others software. Some people here use frewares and get some nice results.
