Something that I believe would immensely improve the game is if players could optionally submit name lists for their nations. Instead of using completely random and meaningless names, each player could populate their nation's name lists with names that they would enjoy seeing again and again. The default name list should be published as part of this as a "base file" for players to use. Players could even share naming lists between one another for in-jokes and/or regional culture.
If a nation had a name list submitted, that would change all the @@RANDOMNAME@@ items into names drawn from the submitted name list. Then instead of names like Zeus, Ryan, and Farnsworth, we'd have individual variations of naming like real nations do. Players could use this to represent part of their nation's culture, or load it up with arbitrary indicators of their national governing policies for in-the-moment-reminders as they're picking issue responses. If players implemented the 503 McGoohan rule and then wanted to implement it in their nation, they could do that with a little work. If a player wanted all the grand high muckitymucks manipulating national leadership to have pokemon types for last names, that would also be possible (haven't you ever wanted to meet a Faith Charizard?). If they wanted really spectacularly rude names, since the name lists aren't publicly exposed, that should be possible too.
