I found a modded server where you can make your own nation and run it your way.
You can set up a government make laws and create ranks for your people. If you do not want to start one you can join a nation that already exists.
It uses the All the Mods 10 modpack and it says version 6.1. You need to get whitelisted first then a staff member helps you get started and gives you a beginner kit.
I found Iperios and it is a modded server where you can make your own nation. You can pick your own kind of government and make laws and ranks too.
If you do not want to start a nation you can join one that already exists. It feels like a mix of survival with people trying to run their own little countries.
It uses the All the Mods 10 modpack and it says version 6.1. You have to get whitelisted through their discord first.
When you get in a staff member will guide you and give you a beginner kit so you can start playing.
I found a modded server called Iperios that runs on All the Mods 10 version 5.5. The main idea is nations where players can make their own group with a government plus laws and ranks.
If you do not want to start your own nation you can join one that already exists. To get in you join their Discord and ask for whitelist then check the new player info channel for what to do next.
After you get whitelisted a staff member helps you and gives a beginner kit so you can start playing. You need the ATM10 modpack installed on version 5.5 to join.
