I found a realistic medieval style towny server where a group of friends just started their own town.
They are trying to recreate Bantry from County Cork in Ireland and they want more people who like medieval stuff to come build with them.
It sounds like a chill group project where you join in and help the town grow over time.

I found a geopolitical roleplay server called EarthPol that uses a 1 to 326 Earth map. Players make nations and do politics and diplomacy with other groups.
There is a nation based on Louisiana and they are trying to grow it. They are building a New Orleans style town with ports and more builds.
They want more players to help found new towns in Louisiana and they can fund it with gold. It sounds like a server for people who like roleplay and building and also arguing in politics.GG.MINEWIND.NET New Server IP
