Exquisite corpse mapping

[Azélor]

Nah. I use 3+ softwares for one project, as long as the next stage works on a flattened raster image then it's good to go. I imagine it would be sorted out like "you do the border, and you do a compass and legend, and you do a world map flat base with a texture and water, and I'll draw the mountains and forests, and he'll draw the small landmarks, and she'll finish it with the text and placing on the border pieces and compass and legend pieces which were given as transparent pngs."

Or you do it like the legendary game I used to play as a child, which involved co-creating an animal by accordion-folding paper, marking where to 'continue' the shape out on the blank, and each person does a vertical stripe. On your turn you fill in your stripe and make a base that shows where the river/lake would enter the next stage of the map, but, they're blind to what is going on, only that the river enters here, the sea starts here, and it's up to them to put whatever they want in their segment apart from obeying where the starting lines enter. Then at the end it's assembled into one magnificent strip.

This would not be a good 'mapping challenge' in the monthly themes, but it would be a fun forum game.

To make a decent map out of it, we'd have to agree to use the same color of ink, and ideally the strips would be backed with a seamless texture that just happens to be exactly the width of one strip. That way it could be assembled in the end with the least amount of seam.

My idea for this would be that everyone who contributes adds the location in the world that they're from, or something that represents it, in their continuation of the map, as well as their favourite map features. Potentially it could carry on forever, becoming a huge banner-length map that represents slices of the works of dozens of members of the Guild.

That is pretty similar to to Guild Wolrd.

Having looked at Guild World, I would say it's similar but not the same. This would be vertical slices passed, done with the intention to connect pieces together rather than individual little country/province designs which all stand alone. I've done it once with continued comic strip panels where we gave 'a little bit' to work with for the next person's lines as a hint of where to draw the continuation of the background. But... it might work much better in comic book art too, who knows. Just like your suggestion, the attempt would be to get something with a unified texture / style but it would also have limits of where people would be drawing, instead of 'add some things wherever you feel like without drawing over anything'. That could also be fun, or chaotic, who knows, I haven't done anything like that since I was a kid when I used to draw with a friend.

Do whatever you think would coordinate in a pleasing and fun way for participants.
