This remix is mostly to have a single 3MF file containing all the files required + preparing the color changes for the divider titles.

13 colors are used to approximate the colors of the civilization. You just have to pop the appropriate colors in the AMS and do the matching when launching the print for a given plate.

I tried to optimize the plates to have max 4 colors per plate and group objects with same colors to minimize color changes.

If you have more colors available than me, you might want to split some of these groups, mostly green and blue dividers.
