By not-so-famous countries I mean those you don't usually find in novels, movies, TV, magazines, etc.
One example is Chile (the place I was born). I'm not sure about America/Europe but if you go to Asia and say you are from Chile, almost no one will know where it exactly is or what language the people speak.
Another example is Taiwan (the place I'm currently living in). Most people (OK, by most people, I mean those that I've met) think it is just a province in China. Others even confuse it with Thailand.
So my question is, do novels that are set in countries like those mentioned above sell less? Would they sell more if they were set in more popular counties like America or Japan? (assuming that the audience includes people from all around the world).
