Why 37? I wanted to give room for multiple, more well known cities within countries such as Limmasol or Aqaba, while limiting the number of obscure cities overall (it's still quite a challenging quiz, however). Turkey is in light grey, as one of its provinces is defined as Levantine, Hatay. Also, don't take this quiz for my opinion on Palestine, or Northern Cyprus for that matter.
Thank you, I don't know if I can call it a series at this point, seeing as most regional city quizzes have already been made, but I like making these :)
