I have some cool ideas:
Create a method of saving maps via png (and reload them later) (plz I need this)
Create alliances, and actions based on previous actions (for example a country tries to conquer another country, it fails, and after the country that was attacked it will attack whoever attacked it before) (it's strange but it would be nice)
Forcing some countries to make peace with each other or make an alliance
To be able to spawn a country with a specific width (e.g. spawn the united states larger than some other country)
Add custom flags to countries
Select which country will win the game
Create other maps e.g. (asia, africa, america (separated between north and south), antarctic, oceania)
It would be great if you add some of these ideas, this is a really great game!
Keep on!
