Do you love typing so long and fast that your fingers ache? Have you nothing better to do for the next hour? Draw the map of the world by entering ALL country borders, including seas, oceans, gulfs, bays, lakes, and of course other countries.
As someone already said, please accept all abbreviations that are usually accepted (e.g. DR, NZ...). Also please accept Holland for the Netherlands since that's usually accepted too and maybe consider adding the usually accepted misspellings.
this took me 16 minutes. and 15 seconds.
and i want to die.
Also, I think some of the -stan countries accepted -stan instead of -sten.
