I love the extended Civ options but I was bummed to find my home country the Republic of Palau was missing. I understand very well that most people probably never heard of it. being small and with a population of around 20,000.
But it really bugged me when Nauru; another island nation with half the population of Palau is included. And don't get me started on Rapa Nui with a population of just 5,000...
( no offense Nauru & Rapa Nui

Also for the Civ flag of "Micronesian" it is the 4 stared flag of the Federated states of Micronesia (4 stars being the 4 island states of yap,Pohnpei,Chuuk,Kosrae).
It would be egregious if its meant to represent Micronesia as a whole region. May I suggest the flag of the "Trust Territory of the Pacific Islands" which is same flag but with a total of 6 stars. Representing Yap,Pohnpei,Chuuk,Palau,The Marianas and Marshall islands. in the end, Ethnically We all are, And call ourselves Micronesian but generally we go by our island nationalities of course.
