Himaruya has his reasons. You may be upset your own nation has no appearance though before you get mad. Look at the personalities of the nations; they are biased stereotypes. But a lot of people like that, though many just like it for its sometimes accurate historical facts or its comedy. Also their are over 251 nations (counting micro-nations, without Sealand) so trying to keep track of over 251 nations would drive one nuts.
