Countries of the world in alphabetical order after all neighbors
Start with the country that is first in alphabetical order. Then you have to submit all of that country's neighbors, also in alphabetical order, before moving onto the next country and its neighbors.
If a country doesn't have neighbors (island, or all of it's neighbors have already been answered), just move onto the next country in alphabetical order. If a country has already been submitted as a neighbor, move onto the next one.
Every country is an answer once only.
