Evil aliens have decided to kill everyone on Earth! Fortunately, they've given you two minutes to save as many as you can. All you have to do is name a country to save everyone in it.
Cool concept! Maybe you can add a little bit more time and censor the names. Felt like I could just read the names at the bottom of the flag for ~90% of the quiz rather than recognizing identifiable icons of the country/state/city the flag is supposed to represent.
