I found a modded SMP that is all about geopolitics on an Earth style map. It uses a Create based modpack with lots of addons and extra mods like Superb Warfare Agricraft and Simple Planes.
The main idea is to found your own country and try to grow it. There is a land claim system so you can claim a country for yourself as long as it is not already taken. You can also bring friends and run it together.
It feels like a mix of industry building and military power. You can build up big factories and machines then push for world domination if that is your thing. If you want politics conflict and people making deals then breaking them this server seems made for that.

GG.MINEWIND.NET New Server IPSemi Anarchy Death Dimension Nations
This is a semi anarchy style server with a really weird death system. When you die in the overworld you get sent to a different dimension but you keep your items. If you die in that other dimension you lose everything. So you have to be careful or you are totally wiped.
There are three big nations you can join or you can just play alone. Interdimensional Raiders is the one for bounty hunters. They focus on hunting other players in the overworld to gain power and items. Sunburst is more for PvE players and they cannot be targeted by the raiders and just want to explore and learn about other dimensions. Xing is based on Fullmetal Alchemist and if you start there you begin with custom abilities and you have to build your whole progress around those abilities.
Right now the server is a work in progress. The owner keeps it online as much as possible and is still testing stuff so some features do not work yet but they are being worked on a lot. Custom items and mobs are planned and are coming pretty soon.
There is a 20 player limit at the moment so it feels like a small community. The only things that can get you banned are if you purposely try to lag or crash the server. Pretty much everything else is allowed because it is semi anarchy.GG.MINEWIND.NET New Server IP
