Using the "Countries Of The World" names.
Ex. Lets say there is a country called "Durpero" and another name for it is "Darp". If the Countries of the world quiz says it is "Dupero" I will put that in regardless that the other name will be accepted.
Start by naming any country that France borders. Then name any country that borders any of those countries. Then keep going until there are no more countries left to name.
