The list of civs is specifically designed to be optimized for the Giant Earth map in Y(n)AEMP. It fills the entire map with civs instead of having large empty spaces on it like Siberia.

Special thanks to TPangolin for giving the list.

How to make your own AI-only game: http://goo.gl/k3lfdh

If making an AI-only game, I recommend spectating as Polynesia/Tahiti because of a glitch that makes civs disappear attempting to do so. They're an island civ, so they wouldn't be very relevant in the world.

Recommended mods:

Y(n)AEMP + leader fix
