...and what happens when you get to a spot where there would be an edge? You wrap around to the other side! You can hold down the right arrow, and see the exact same provinces, forts, armies, etc. 100, 1000, or even a million times if you've got the patience. It's not that they're multiple copies of those provinces etc., it's that you're seeing the same one over and over again. Imagine if you had a hovercraft and you were piloting it around Earth's equator. If you went far enough, you'd keep seeing South America. It's not like there are a whole bunch of copies of South America, though, there's just one and you keep seeing it over and over again. The game does let you zoom out to see up to two copies of the map; this doesn't somehow duplicate anything, it just lets you get a nice strategic overview. And the wraparound maps of Dominions are painted on a torus (a "donut") rather than a sphere like Earth.
