Hi, two small errors we found. The second largest of Iran is Mashhad not Mashdad as you have it. Also please accept St Petersberg as well as Saint Petersberg as on the map of Russia it was displayed as St Petersberg (not that we were looking during the quiz)
Fixed those two now. Thanks for letting me know. I already discovered another mistake myself, I somehow got Bosnia & Herzegovina and Bolivia switched. Of course that's fixed now too. Don't have that much time now, but I'll go through all of it once again within a week or so
Great idea!
