Title is pretty self-explanatory, I guess. I made President tonight, so now I have two towns and a Nation named Arcadia. Which is neat, sure. But what is the nation? Does it do anything? Or is it just a fashionable accessory? My apologies if this is already answered somewhere. I looked for awhile, but it's late.
A nation name can be used as the name for your chat channel. Other than that, not much. If you can think about anything that could be added to make use of nations, we're all ears!
I hope that towns under a nation name should be "parented" under the nation name, so they have a real purpose and people can see that the towns are officially under a nation. This is simply a suggestion to SAs and physicistsmom.
