The website I got these from included Guinea-Bissau so thanks for the correction. But the USA is classified as United States as the main name so that will not count.
I still don't understand why you accept Federated States of Micronesia and not United States of America. It's the exact same structure (Something States of Someplace). Simplifying the rules wouldn't even expand the list much. UAE, Sao Tome e Principe, UK of Great Britain and Ireland, both Congos, St Vincent, St Kitts... none of these end with an A in the long form.
I understand that, but Micronesia ends with a either say so that doesn't matter which way its put in, the US, I still consider ending with S and not fully the "america" with full names, but I will keep that standard consistent from now on.
I agree with you that it should be Myanmar, since I got it from a website, this list, I just added Myanmar to be answerable as well. I Honestly didn't think about just not including it. Thanks
Aside from that, great quiz!
But I think Jetpunk still uses Czech Republic, so maybe Czechia could be automatically filled-in / greyed-out on this one?
