Great quiz and a lot of fun. I second the suggestion that you do other continents. One small edit - you note 50 countries in your description at the top, but there are only 45.
Andorra is missing the arrow which other small countries have. It would be great to add it. I was stumped, scrolling around for a bit and thought the quiz might be broken for a while, until I finally found it.
Why do non-Americans always start every complaint about anything in the world by assuming it's an American phenomenon and choosing the (often incorrectly) perceived nationality of the 'offender' to whine about?
