Couldn't figure out why Yangon wouldn't work - forgot about Naypyidaw. (I finally remember it's now Yangon instead of Rangoon, and then they move it to a different city. Sigh.) Great quiz.
The quiz instructions should mention that city names ending in "... City" need to be typed out, as this is uncommon on Jetpunk. Alternatively, the cities ending in "... City" could be shaded a different color and/or pre-print the word in the list of answers.
