You know the rules... They're exactly the same as in every other thread. But... this one has countries. All suggestions go on my profile [even countries that don't exist anymore]. Let's start with the first one.
We already have loads of 'Battle of...' threads (which aren't exactly my cup of tea, but that's fine). Adding another one seems a little absurd. That being said, one about countries could lead to potentially harrowing situations and angsty people.
