Very interesting and fun quiz! There was no explanation as to why the asterisk was in the quiz so it was impossible to guess Hong Kong just based on the list of sovereign nations. It'd be helpful to have that explanation in there.
Why do you keep putting Hong Kong on all of your Quizes. Do you see how many people are commenting about how you should take it down. It is NOT a country, it is an Autonomous region of China. If Hong Kong is a country than so are Wales, Scotland, French Guyana, Guam, Porto Rico, Tibet, Basque and Catalonia.
