I bet if go down to county or city level, you‘ll find differently colored areas such as cities relying on old steel, coal, textile economies. At least here in Germany I know areas where many people left their home areas in the 90ies. But that’s probably a geography lesson.

If you‘re so picky, I‘ll as well. I wrote it spans across, not includes all.

And France is the only one country that spans across all time zone on the globe.

One of my first games. I stared at those moving lines for a long time.
