I found this server and it feels like super realistic city roleplay. It started as a democracy government simulation and players take the politics stuff really seriously.
The economy gets wild too. People even reinvented credit default swaps from scratch and now there is a second bank collapse happening. It is the kind of place where you can learn a lot but the learning curve is huge.
If you like watching big player made stories happen then this one is worth checking out.

GG.MINEWIND.NET New Server IPBuild a Nation in Modded ATM10
Iperios is a modded server built around the idea of nations. You can make your own nation and pick your government style. You can set laws and create ranks for your people.
If you do not want to run a nation you can join one that already exists. A staff member helps you after you get whitelisted. They guide you and give you a beginner kit so you can start playing.
The server uses the All the Mods 10 modpack on version 5.4.WebsiteDiscordGG.MINEWIND.NET New Server IP
