Hey everyone, I've been working on a procedurally created adventure game and wanted to have world maps that gave the impression that they were hand drawn. This was my process if you're interested:
Here is how the maps started out:
Each square is a zone of terrain, the roads connect major points of interests, like towns, temples, dungeons, etc. The terrain can be deep water, shallow water, grassland, forest, mountains, etc...
Here is a mockup drawing that I did by hand that captures the design intention:
I took the rigid square layout and added noise around the square edges, colored the terrain a canvas color, and applied texturing:
There are points where terrain squares connect at corners causing the islands adjacent to continents to be connected at points. I updated the edge noise algorithm to chop off those corners to break apart the islands and continents. I also applied a bit of lens distortion:
A bunch of different procedurally generated world maps:
Lastly I made sprites from my hand drawn map and added some icons and city names that are all procedurally placed. Here's the in-game version:
