I don't think I understand the point of this. I colored in the players for US, Russia, and China (should be that way by default I'd have thought). But I have no idea what to "simulate".

I do see in the site meta that it's purpose may be to just fill in so you can see who would have what population and area if an alliance was formed or area was conquered, but even that doesn't seem to work as selecting the US registers 0 population and 0 area.

I don't understand it either.

Map Painter? I am also seemingly missing the point.
