I do have a minor issue with the title, however. I wasn't immediately sure what the quiz was about when I looked at it the first time. I might be alone here, but perhaps it would work better as "Non-Jetpunk Countries Participating in International Sporting Events" or something to that effect?
Good quiz, nice work. Palestine isn't a UN member, by the way, but I think it's considered as a country on Jetpunk?
That one threw me for a loop! But you're absolutely right.
