Here is Māinṃ. It's a world I started to build on for a small game project.
This thing devoured all my free time for a few weeks, until I got to a boring part (lettering), when I didn't work on it too much for a couple of weeks, but now I got back to it and it's basically done enuff.
If you want to know more about this particular world, check out the WIP thread.
Diameter: around 18 000 km
Map projection: no projection
Programs used, in order of most useditidy:
GIMP (most everything to do with land-masses, and the mountains, trees, etc.)
Inkscape (graticule, geometric figures, straight lines, the small heraldic emblems, the corner diagrams)
MyPaint (lettering and the later small pictures)
The writing script: Latin-derived miniscule, original for this project, made by me.
Language on the map: Proto-Finnic etymological forms w/ modern Finnish syntactic and morphological constructions run through a set of sound-changes.
