Updated 20/1/17. Adds all UN member states + 8 more.

1. DESCRIPTION
Adds 166 nationalities to the game as if they were always included, with: 
-Flags 
-Names and surnames (26000+ across 118 custom namelists) 
-A custom rebalance of all the game's countries' UnitWeight (chance of showing up), even for default nations. See the ReadMe for UnitWeight details.
Together with the game's default nations, they make up ALL UN MEMBER STATES plus the British Home Nations, Hong Kong, Kosovo, Palestine, Puerto Rico and Taiwan.

2. COMPATIBILITY
- Compatible with all DLC (up to Shen's Last Gift, at least).
- Compatible with Long War 2.
- Compatible with other nation mods, even if they add the same nations, due to MNM countries and namelists using a unique identifier. You would obviously end up with duplicate nations.
- Conflicts with mods that alter the UnitWeight of default nations. See the ReadMe on how to compatibilise.
