You got 82 out of 195 Countries of the World.
Would've guessed more if it was in Dutch, I had no idea how to type/name a group of about 10 countries in English.
Was most clueless about Africa and about the islands in the pacific/ east of Indonesia and Australia.
Missed a lot south American ones too.
And generally missed a lot of island nations.
Think I only got 7 African countries ( though thinking back I could have named much more but somehow I completely blacked out on trying to guess African countries.
Europe was complete aside from rubbish nations like vatican city ( and some I didn't know the name of in ENG, like the 3 countries above poland, estonia, letonia or well whatever, In Dutch they're Estland, Letland, Litouwen ( north to south), and chech repub it somehow refused to accept it) .
Knew the whole middle east bar 2 entries ( though didn't know how to type Afghanistan and didn't know how to type stuff like bahrein )
NA was pretty easy just 3 countries

.
Knew most of asia.
