I tend to use the most commonly used name of countries, and since the republic of congo is more commonly known as just Congo, I kept it that way. The DRC has to be called that to differentiate it from its counterpart
I get it. But if you're using a formal name to distinguish a country from another country's informal name, then the quiz seems a bit off. Personal opinion.
Perhaps after 4+ years on here you might like to contribute the odd quiz instead of telling people you think what they have done is off. Personal opinion!
Hi! Always nice to see letter quizzes, but we have moved from Czech Republic to Czechia (which is the official country name in English), so one less on the list.
