Is this hard enough, though? I got all 20 in 45 seconds, with many typos and deletes. I admit to it being a challenge, but not necessarily difficult -- perhaps some Oceanian nations will demote the average score..... :-)
It is not hard for some of us, but I think it is for people with less geography knowledge. So it can be challenging and fun. Not all of us are experts. Nice quiz and thanks :)
Still very easy. But I think for many people on this site, there would be no such thing as a hard version of this quiz. There aren't any countries in the world I could not easily identify on a map except maybe some of the tiny Caribbean and Pacific ones.
