I added Costa Rica, Vatican City, and Czech Republic, (even though most call it Czechia). F.S. Micronesia goes by Micronesia on JetPunk, so it's not in the quiz. If you read the description, you would see why El Salvador isn't in this quiz.
Not in the Czech Republic they don’t. A lot of Czech’s really take exception to ‘Czechia,’ I’ve made the mistake of using it in front of my Czech partner before and the response was something along the lines of “Jdi do prdele!” I’ll let you translate that yourself, if you’re interested!
