But what's the point of not zooming in the guessing map (in the top right)? That's just the interface for giving the answer; and restricting zoom just makes it a pretty poor mouse accuracy game. If you know the exact position, you should be given the interface to mark it exactly.
And it's also a bit of a geography test. I guessed Moscow (wrongly, it was Minsk) and had to test my knowledge of where in the giant unlabeled shape of Russia that was. Similarly, pinpointing Montana out of all North America (with no country or state boundaries) is a lot harder than guessing "somewhere in Montana" when you can see the outline of Montana.
